Sounds like a great sports / guys weekend! Last year my neighbor and I did Michigan State @ Michigan on a Saturday......followed by Redskins @ Lions on Sunday (he's originally from West Virginia and a Washington fan).
Unfortunatly, I can't help with tickets (it will easily be the toughest ticket this season! Cutler's 1st game at Soldier Field, Home Opener, World Champs)
One of the best places to go before the game is our Tailgate Party (see website below). We haven't updated the site yet, but we are doing the Steeler game for sure.
After the game, your best bet is probably to get to one of the many bars inside the hotels. The Sunday Night game is NY Giants @ Dallas (first game in their new stadium).
