There are so many tips....let me start with saying if you have many similar shots, you can save your raw tweak for one and then in the browser, select all like shots and apply that raw setting.
I shoot allot of indoor with bounced flash, I started noticing I was always had a certain WB temp of 5100K, so I use the "K" mode on the camera on WB and manually set it to 5100K and that pretty much eliminated having to do tweaks for these shots. The more I shoot, the less post processing is needed.
There is also a trick that you can get away with more sharpening if you convert to LAB color and only sharpen the lightness channel instead of all the channels together.
I break my actions up into little modular parts (must me my software engineer side coming out). I have one action that just opens the RAW file...I then call this action in another action....so you see if I have allot of simular things going on, I can tweak just the one to affect all that call it. One thing to note is that you can have sets of actions, and if you move an action from one set to another, the action that calls that action will have to be fixed because it calls actions from a specific action set. It's important when your create a "open raw" action to make sure you have "selected image" (or something like that, don't have PS open at the moment), and not "camera default" so that the raw will open with your tweaked changes.
Oh ya, and if after your tweaked your raw file in the raw converter and when it opens in Photoshop it looks faded....you don't have your working color space set to Adobe RGB. If your opening your raw as Adobe RGB, you should set your working color space to that or it will look different. You can always then covert it to normal RGB for web in an action or something.
