If you're not a newbie then shoot in manual, and avoid all the digital issues. Set your flash to a FEC of -1 1/3 or so, it'll help fill in the shadows.

Digital can be used just like film, except your exposures need to be a lot more accurate.

If you are used to using the 350D you may be best to use that until you know how to use the 30D better. It's not a huge change and in fact the 30D (which is almost the same as a 20D) is easier to use than the XT but you may find you miss shots scrambling around trying to find the odd menu item or button.

If you can get to use the 30D before the wedding you should get up to speed with it pretty quickly though.
