Actually I believe that the chainring bolts are on the backside of the crankset and that the chainring

OP: I run a compact road crank on my commuter MTB with a 34/50t and a 11-26t cassette. Where I live this works out great but you might want an 11-28t or an 11-32t, which your current rear derailleur should handle fine.
