Could someone please walk me through how to custom WB? I will be shooting basketball in HS gym that has miserable lighting. Yes, I will be shooting in RAW but would like to get WB as close as possible to avoid unneccessary manipulation in post processing...thanks...Yvonne

I can't walk you through what to set. But I wanted to try to help and offer some ideas. I would suggest shooting a neutral grey card such as a WhiBal or similar, and you'd have that to use for post processing. If the light is somewhat consistent, then you'd be able to adjust one photo, and apply the adjustment to the remainder of the photos in a batch process.
Another idea, is if you have access to the gym before the game (like a day or two before), shoot some shots on various settings of WB. The D200 allows you to set specific Kelvin settings, so you could shoot quite a few different values, and determine what works best. If possible shoot as near to the time of day as when you plan to shoot the actual game(s), in case ambient light from windows might have an effect. Also, if there's any chance to include uniforms and some players in the test photos, that would help. (Maybe you can attend a practice, and shoot then.)
If you have a son/daughter or friend on the team, having a part of the uniform to compare to on-screen image (calibrated monitor of course) or a printed image would really help.

The problem is not "unnecessary manipulation", since you will have to do some manipulation and it does not matter if you are adjusting your white balance by a lot or a little. What is a concern is getting the exposure right because you don't want to clip your highlights but you also don't want to underexpose.
For the best advice I have seen anywhere on this check out Julia Borg at DPR. There is a post here: http://forums.dpreview.com/forums/read.asp?forum=1021&message=21234233 that summarizes well the best approach. If you know what the imbalance in the lighting is, you can get a filter to block out some of the dominant light so that all the color channels are balanced (particularly the blue channel, where most of your noise occurs).
