Random questions regarding downtown Atlanta and the ACC Tournament

[Bearcat]

1) I'm going to be there for a little while. I know Simply Red, dtebbe and a few others on this board live there. I should have plenty of time to look around... what would you recommend downtown (or within a reasonable distance from downtown using public transportation)? It looks like there's a ton to do, so just trying to narrow it down a little. Opinions on nightlife (Underground Atlanta?), local dives/restaurants, touristy stuff, etc; would be appreciated.

2) Re: ACC tournament... has anyone ever attended a basketball game in a football stadium before? Is it worth it in terms of being able to see the action? The Georgia Dome configuration doesn't seem so bad (as opposed to Detroit, where they put the court at midfield ), but I'm looking for opinions because the full package is like $400 (and I'd probably be able to make ~5 of them). The pic doesn't look all that bad, but again, just looking for opinions (and if anyone is looking for afternoon games on Thursday or Friday, you can have mine if I buy the entire package).

3) So, I found ACC tourney tickets available... row 1 of section 333. I can't buy them quite yet because it's not 100% that I'll be there before this weekend, but section 333 happens to be one of UNC's sections. Is it wrong to wear a Kansas National Championship t-shirt while sitting in the UNC section of the ACC Tournament?
