I had a 2009 Zesty the same as this that was upgraded with the following, I had XT Cranks on a 36 single ring with a MRP guide, a 11 - 36 cassette on the rear. Wheels were Mavic 819 rims on Hope Pro II hubs, I would leave the forks on it as they really do suit the rear shock and anything else would probably upset the overall feel. Hope this helps.
