Kristine is right on, jerseyguy. The expense ratio is the annual fee you pay the company to manage the mutual fund. Anything under 1% is good. Under 0.5% is great.

Lifecycle funds haven't been around enough to really gauge their performance, so it's hard to say which will do better in the long run. I personally prefer Vanguard but you'll do just fine with the Fidelity Freedom funds too.
