Heh Vonnagy, I do the same thing you do pretty much

Here's the specifics.
I develop my RAW photos with C1 Rebel, and I pump up the saturation there as much as I can without gaining noise, and then I use a hue/sat adjustment layer in PS afterwards, which is sort of the icing on the cake.
Colors always look deeper when you have nice contrast, so in that respect, curves are your friend. Also, USM at 40%, 20, 0 adds a lot of contrast and can make colors appear more vivid.
I agree with what you said about dodging and burning too. I don't use the tools. I find it much easier to use several curves adjustment layers, for each part of the photo, and use the layer mask to selectively apply it.
I use color balance adjustment layers when the colors are off, but also I use several of them selectively to different parts of the photo to enhance color as well. If I have a blue sky, I will use a color balance layer and add more blue and cyan to the sky, and just mask it off. One for green grass, etc...
Hope that helps
