What's up St. Louis Game Time?

I am a Stars fan leaving the frying pan that is Texas and heading up to Mizzou for college in a week. As a huge Stars fan, I plan on making a trip to St. Louis to watch the Stars play the Blues sometime this year. As such, I was wondering if your community could give me a some tips on maximizing the game experience in St. Louis.

Things to keep in mind:

• I have family in the St. Louis area so I have a general knowledge of St. Louis itself
• Don't need lodging, will stay with family, or make drive back to Columbia
• Broke college kid, don't refer me to some expensive joint

Main Questions:

• Best place to get tickets (Blues Ticket Office, StubHub, etc.)
• Parking
• Good, but cheap food (I will maul anyone who says Imos)
• Something to make sure to see/do in St. Louis (Seen the main attractions many a time)

Thanks for the help!
