Forgot to say LR also has a transfer to Photoshop tool. In PS it becomes a TiFF, you do your edits and when you save that TIFF files appears in LR again beside the original RAW file. Not sure it will work with CS3.
Yes it will work with CS3 but with some caveats, that change the way in which it happens. Normally where the version of PS is concurrent with or newer than that of LR it uses ACR to render the image to PS as a dataset that exists only in RAM. LR passes all of the editing commands to ACR, as if it were an .xmp file. Once you have finished editing the image you hit save, Ctrl/Cmd+S, and the image is saved using the settings found in your LR preferences, by default that would be a 16 bit ProPhotoRGB uncompressed TIFF file with layers intact. Of course this being Adobe there are lots of options to chose from, I usually keep all of those with the exception of using .PSD. The file will be saved in the same folder as the original RAW, or other file type*, and imported into the catalogue, if the image is not already part of a stack it will be stacked with the original file. If your version of PS predates your version of LR, then there is a problem, since ACR will not be able to correctly render the image, since the capabilities will be different. In this situation when you go to do an Edit in command LR will throw an error to the effect that there is a mismatch in the versions. In this situation choosing the option to allow LR to render the image, and selecting the don't show again option, will allow the image to open in PS ready for editing. The main difference being that you will have to wait in LR while the file is actually generated, just like a normal export, and also as the file is imported into the catalogue, after which LR has PS open the now existing RGB file. When you finish editing and save then it behaves to the user just like the other method, although of course the image file is updated, not created. The main consequence for work flow is that if you change your mind about doing a PS edit, with the ACR render you close PS without saving, and nothing is created. With the LR render of course there is already a file, that has been imported to the LR catalogue, so you will need to manually delete it from both the catalogue, and the drive media.
*You can run the edit in PS command on any file type from LR, including RGB files. In this case you get three options, which I think you see all the time on a Mac, of Edit copy with LR adjustments, Edit a copy, and Edit original. In the first case LR will behave with an RGB file in just the same way as with a RAW. With the copy option it creates the new file first, imports to LR, and opens in PS. The last option of course just opens the existing file. If you open an existing file directly in PS, outside of LR, edit and save then LR will automatically see that the file has changed, and generate a new preview etc when next you view it back in LR. This will also update any virtual copies of the RGB file, and any LR processing will also be applied to the "new" base image. I will often do monochrome conversions and much prefer to use the LR/ACR channel mixing tools, as they have more channels than any of the direct in PS options. So I will do any PS work first on the colour image, and then bring it back to LR and create a VC for the black and white version, so it is important to remember that any changes to the base file will propagate through to the VC too.
If you have more than one copy of PS or PSE installed on your computer LR will usually find all of them, and you will see the different versions offered to you in the Edit in options. One thing I can't now go back and check, as my new system only has the latest PSCC 2017 installed is what happens with the open as Smart Object option. I would think that as it uses ACR as the editor in PS for RAW file types that you would not be able to use it. However IIRC it is still there but just fails to work correctly. Open as Smart Object was not a function I used to use on my old system, as I was very constrained for disk space, and a RAW smart object has to embed the compete RAW file, as well as the RGB Raster version of it into the file, since on that system I started with LR4 plus CS3 and then also had CS5.5 installed later. Oh and if you do install a new PS version, in addition to the version you already have LR seems to find out about it, and you will see it included in the Edit in options, along with the old, and any other image editing programs you might have. Many other non Adobe editors will see the LR install and automatically include themselves during install. With a new computer system it can be beneficial to install LR first, and then the rest of your third party editing tools for this reason. Otherwise you can find yourself having to set up the "Edit in" exports for them manually.
Finally if you are considering the CC option but are worried what you would do with all of your images in your catalogue should you stop the plan all is not lost. The Adobe CC programs are not really "cloud" programs running from the cloud, they are normal full installs just like any stand alone program. It is only the licensing that requires the use of the web. When you stop the subscription the program doesn't stop working, but it does become restricted. You can no longer open the Develop module to edit images, and you can't open the Map module to geo tag, or view the locations of images. Everything else seems to work, certainly all the export functions and the Print module work, I think the web, book, and slideshow options still work too as they are output related, but I didn't try them between my CC trial ending and a new discount offer starting for my plan. You can even still import new images, and if you are happy just using the basic editing tools that are accessible from the Library module in the Quick Edit tab you can actually make basic editing changes too. Adobe will even let you install all of the updates to LR too if you want them. You can even put a copy of the program download on a memory stick, or even a DVD, it's a bit under 500MB IIRC, so that you can install it in the future, although Adobe seem to be pretty good at keeping old versions available for download. Downloading a copy of LR4.4 was the simplest way to install that on my new computer, ready to then upgrade to CC.
