BurtonAvenger's comments are pretty much right on. March is better than Feb, but avoid Spring Break week if you can. Def go with the early bird deals if you can get good ones - the rates are great right now and it would be better than getting stuck far away in some shithole (happens to a lot of folks). I second the King Soopers idea too - unless you can get an awesome deal through the early bird specials.
As for apres, I think Breckenridge Brewery is pretty hard to beat.
Also, if you're there during a week that isn't crazy crowded, you might want to hit Keystone for a day too. It's really nice, it's right down the road, and most ticket packages can be used at either Breck or Keystone. At Breck, if you're hitting the regular runs, Peak 7 used to be the shit, but now they put up a gondola there and it is super crowded, so Peak 8 is a lot more fun and less crowded. Cheers!
