It's not really that kind of party. It's just sort of a gathering of close friends (probably will be no more than 8-9 people) where drinking will also occur, so a keg would be a bit of overkill.
Your best bet then is BYOB... but if you really want to be a good host, go grab, say, a fifth of Skyy Blue, a fifth of Jack Daniels and a fifth of Captain Morgan. If there's gonna be chicks there, substitute the JD for Cuervo.
These are all pretty universal liquors, in that everyone will enjoy one of them. Plus, none of them are sooo expensive that it'll crush you to get them, as the most expensive one is 20 bucks (at least in MI) for a fifth of JD. If you're not gonna go BYOB i'd definitely do that, and maybe supplement with a case of cheap but decent beer, like Coors Light or Labatt Blue. You don't need to go be buyin' a case of Newcastle or Killians, but this stuff I listed should suffice.
If you need beer that you really, really like, I've lately been suggesting Blue Moon. Awesome on it's own but with a slice of orange to go with it, it's heavenly. That's a pale ale (lighter taste). Heavier beer, well... I'm a newcastle guy, though people are split on Newcastle. People either love it (men) or absolutely hate it (women). I've also heard good things about Sierra Nevada.
Though stay away from BandT for awhile.... get your appreciation for beer up.
