Agree on the variables but I was really impressed by just picking up the 20D and shooting..
The corfrect answer is "I don't know".
The correct answer is also "why don't you try some, and see how you like them?".
In all seriousness, that is the way to go - load a curve, and play with some in-camera settings, shoot for a few days, and see what comes out. Change the curve, repeat the process, and keep on doing that, trying a number of different settings and custom curves.
Examine the work on a calibrated monitor as you go - don't use the camera's LCD - it's too unreliable for critical analysis - and make notes about what you like, and what you don't.
Obviously work with what you like - if you like something - and keep going from there.
FWIW, I have most of my WB settings turned down a notch or two, and generally use a realia curve. When using the on-board flash, it too is turned down somewhat - up to 1.3 stops sometimes - in order to just add a smidgeon of light and reduce the contrast ratio in the subject matter.
