Eric,
First, a little chain slap is perfectly normal. Nothing to get freaked out about. On downhill runs, shift up into the big ring to take up a lot of chain and minimize the slapping. This also makes it much harder for the chain to bounce off of the chanirings.
Minor adjustments in chain tension can be made with the adjustment screw probably at the top of the group of three screws at the back of your rear derailleur. This adjusts how much tension the derailleur places on the chain. Monkeying with that may effect your shifting though.
If the chain is really, really flapping it may mean that your chain is worn out or was not properly sized when installed. There's a generally held normal number of chain links per foot of chain that you can measure with a ruler (can't remember how many) to see if the chain is worn, or you could just take the bike into your local shop and ask to borrow their chain checker. I suggest you let a mechanic check for wear and proper sizing.
I hope this helps. Grant B
