Calling for some Keeper League advice

Hello folks,

I joined a Keeper League for next season, my first foray into Keeper League fantasy baseball. I'm fairly current with major league baseball players, but am not as familiar with the minor leagues. The league I joined is having a minor league draft next week, and I'm trying to do a little research before then.

Can anyone out there recommend a good source/sources about the best 2008 minor league prospects? Preferably info that I don't have to subscribe to, but I'd consider it if it was exceptionally useful. The one blog I have checked out is Sickel's minor league blog, which is excellent, but it's also where I found out about the Keeper League, so other sources of info would be helpful.

Thanks.

Oh, and if anyone has any advice for my current roster, I have to trim down to 20 players by tomorrow night, including my minor leaguers and my reserve players.

Curent Minor League roster:
