I forgot to reply to your question about variety. My advice is to keep it simple. It's a wedding, not a wine tasting (or at least I assume it's not -- it might be if all your friends and relatives are wine geeks). For my daughter's wedding, we had one Chardonnay and one Pinot Noir, both pretty good but not great bottles, and I heard no complaints.
However, with the meal, you might want to consider some Chardonnay. It doesn't go that well with Asian food, but for some folks, Chardonnay = class. I happen to think Navarro's 2005 Chardonnay Premiere Reserve is one of the best they've ever made. $22 per bottle before the discount. But there are a lot of other good choices -- just make sure that what you choose is not too oaky -- that would be nasty with Chinese, IMO.
