To answer a couple of your questions that I didn't see addressed...
If you are shooting birds in flight or anything that is moving that you want to track, use AI Servo. If your subject is still, use One Shot.
Metering: I almost always use Evaluative (same as Matrix on Nikon) unless I'm shooting a very white bird when everything else in the frame is very dark. Then I use spot on the bird so I don't blow it out. But there are other ways to handle that as well.
If you are not worrying about running out of CF card space, why not shoot both jpeg and RAW. Then you will have something to play with later when you want to expand your post processing skills. And heck, what if you get that award winning shot of the gator eating the spotted owl and only have a crummy jpeg.

Congratulations on your camera! Exciting times ahead.
Oh, one other thought...you might want to take a dSLR course at
LLU. I have taken all of the ones offered by Kathy Adams Clark and have learned a ton from her. There are other good instructors there too I've heard.
