I don't know if these functions are available in PS 5, but if they are, then they'll work great. For soft focus, Gaussian Blur is the best tool usually. Personally, I like a Distort Filter called "Diffuse Glow". It adds softness, grain, and glow; it really gives a nice vintage 40s/50s look. I also prefer it because I find I can control the effect more with it.
Chances are that you do most of your work in RGB mode. I like to switch to lab color, select the Lightness channel, and use Diffuse Glow there. Apparently it maintains color tones better. It could also be my imagination. As far as the tan look; you could try warming up the image with Curves, or upgrade to Photoshop CS which has a Warming filter built in. Sorry I dont have more for you on that one. Hope this helps! -Austin
