Flywheel and Clutch

So my clutch is going out, and I hear its a pain in the ass which is awesome. I tend to make really easy jobs insanely difficult so maybe this one will kill me. I will be prepared if it does not however and put in a good clutch. I want to replace the clutch and flywheel. Im currently around 345 hp and plan in the quasi distant future to get it to 600whp. Currently I do alot of dirt play so I do put it through hell. Any advice?
