OMFG, so true.
Bally's is a nice loose 1/2 room with good traffic. I was there on a light Vegas weekend and it was one of the only rooms that was usually near full.
MGM was nice a couple years back when I went. It used to be my favorite room when I stayed at the Luxor. Big room so game selection was good and it had its fair share of terrible players.
I saw Caesar's room the last time I was out there and they have done one hell of a job with it. Very nice. Although, since it is a dedicated poker room, walk-in/fish traffic is probably less abundant.
Bellagio is always packed. I assume it has plenty of regs.

As for bars/clubbing. The Palms and Hard Rock are probably your best bet. You might try asking any bartenders/waiters that you have about the best clubs. They usually know other people in their industry and can point you to the hot spots or sometimes know bouncer/bartenders/dancers that can get you a deal for bottle service/VIP or even free covers.
