I have some comments on some of the posts above:
Camera RAW's largest benefit, in my view, is you get a digital negative. You don't have that luxery in JPEG.
I shoot most of my stuff with a Canon 100-400 IS. If I really want a close-up of a distant critter, I add a Canon 2x Extender. I can't hand-hold this and need a substatial tripod. There is a new, updated version of the Extender comoing out from Canon. I haven't seen anything in the stores that I use. With the extender on, it doubles the focal length of the lens. The extender is compatable with fixed L-lenses 135 and up, and 70-200 and 100-400 zooms.
Training vidios is a crapshoot. For Photoshop CS and CS2, I used Total Training with Deke McClelland. I was quite happy. For CS4 I used Total Training and I was disappointed. I just got CS5 and I did some shopping. I ended up geting a video from Adobe Store. I'll have to wait and see how it works out as it is in transport.
A note about Adobe and upgrades: The upgrade policy has changed. Where you used to be able to go back a few versions, you can now only go back 2 versions, ie, to CS3, CS5 is looking good, but it is too soon to tell.Bridge has been upgraded and does some trick things. RAW processing is easier to use.
On a normal day in Yellowstone National Park, I shoot 300-500 shots on my Canon 7D. On my old 30D, it was 250-350 shots.
