Don't overcomplicate it. Green can be any green, doesn't matter what. Make sure you light the screen evenly and try to light it separate from the subject; the more distance between them the better. And have at it. Do a test shoot before a project you really care about.
 
Vegas probably has the best keyer of any NLE, but there are better keyers in different software, like Keylight in After Effects.

No, it doesn't have to be an exact shade of green. It doesn't even have to be green; it can be any color. Chroma green is generally used because there is the least noise in the green channel on video equipment, and because that shade of green doesn't usually appear in the subjects you'll be shooting (like skin tones, hair tones, etc.).

As for rotating 90 degrees, you can; but your subject will be limited in movement from side to side, and it'll take a bit more work in post. But you may find it gives you better results. Experiment.

Shoot THIN and progressive.

Even lighting is very important. However, you can crop out part of the screen and not have to worry about that part (you can use a Bezier mask in Vegas or After Effects) -- this is called a "garbage matte." You just get rid of any part of the picture you don't want and really only have to worry about keying the area right around the subject.

Make sure the screen is lit brightly enough to give you a good, bright color, but not so much as to overwhelm the scene. The subject should be a bit brighter.

If you use the marker in the DVX, have the screen lit at about an even 60% and the skin tones on your subject (if light-skinned) at about 70%.
