If you are happy with 5D classic, keep it. In fact, maybe pick up a second one to have a backup. So long as it's meeting your needs, if the newer models are not offering anything useful and might even be a problem, you don't have to
"upgrade". 5D classic is still an excellent camera and AFAIK, Canon still supports them fully in their service dept. (someone please correct me if I'm wrong). Independent repair shops will probably support 5D classic long after Canon doesn't.
If the file size of the 5DII is a problem, the file size of the 5DIII will be too. Yes, you can scale them back to mRAW or even sRAW, but that's not your only solution. For one, maybe your computer isn't as up to snuff as you think. Heck, my image processing desktop computer is about 4 years old, nothing all that special : PC with 64 bit Windows 7, dual channel Petium 2.2Ghz processor, a RAM upgrade to 8GB (maxxed out), a graphics acceleration card with 1GB of memory and few other tweaks. I sometimes use a laptop on location, too, which has less RAM (4GB at present) and doesn't have a graphics accelerator. It's fine... sort of depending upon the software.
Do you use Lightroom or Aperture? These and some other similar programs can really streamline your workflow, allowing you to do light image editing and selections, batch process RAW conversions and produce proofs in print or as digital files... so that you only need to do the slower and more detailed Photoshop finishing work (if needed at all) with the final, customer selected images. On my desktop, I have both Lightroom and Photoshop, as well as some other imaging softwares. My laptop only has Lightroom... I don't use it for the more intensive Photoshop work (a laptop is not great for image editing anyway, since we use them under all sorts of lighting conditions and the viewing angle of the smaller screen is so variable).
You are right about the AF system of the 5DII vs the 5D classic. It was a big disappointment when the 5DII was first introduced, that Canon had made no effort to improve the AF. They had already introduced 40D and 50D, which saw significant AF improvments over the 20D and 30D that paralleled the 5DC. So there didn't seem to be any excuse for not improving the 5DII, too. Sure, it got a couple generation newer processor, but because that shares image handling duties along with AF, the larger files sizes of the Mark II sort of nullified any help that might have given the AF. Maybe Canon considered it "adequate" for the FF camera's intended purposes or left the AF unimproved to help keep costs down (better AF, among a few other things, appears to have added $1000 to the cost of the Mark III). Or, maybe Canon was hoping those who wanted FF, 21MP and great AF would ante up the $7500 for the 1DsIII instead.
I never owned a 5D classic for several reasons.... different from yours. I often have to shoot in dusty conditions and already was having enuf problems keeping the sensors of my 30Ds clean. The 5DC had a reputation as a dust magnet. The 5DII has a self-cleaning sensor that made a big difference, for me. It also has a number of other nice, if incremental, improvements over the 5DC (better battery tech, video capabilities, much improved LCD monitor, 21MP/14 bit vs 13MP/12 bit, etc., etc.) Some of those were important to me, but may not be important to you.
If you only have the two lenses as you seem to indicate, then IMHO definitely you should consider expanding those first, before upgrading your camera (though if you shoot for pay, you should have a 2nd 5DC). The 135/2 is a wonderful portrait lens... I ordered one along with my 5DII, since I knew I'd want it (already had 20/2.8, 28/1.8, 50/1.4 and 85/1.8). I was returning to full frame after some years shooting only crop cameras, but I knew from shooting film (i.e. "full frame") for about 20 years prior to digital, that I'd definitely want a 135mm... and the Canon 135/2 is a superb lens.
A little more food for thought... Personally, I'd sure want (and have) something wider than 50mm, too. A 35mm, 28mm or even wider is handy for environmental style portraits, showing people in their surroundings, at work or whatever. It's also good for group portraits. Of course, you have to be careful of various wide angle effects when shooting portraits (don't get too close, avoid positioning people too near the edge of the image, etc.)
