I will add that you MUST get proper wheels. I was an athletic 250lbs when i got my first bike in years last year. I didn't have major issues with the wheels but after 8 months i discovered cracks in the rims. What i find on bike forums is people always recommend Velocity deep v's however, I would actually recommend a Velocity Chukker which is designed like a deep v but wider so it can accept wider tires which will add a lot more comfort to your ride. Getting proper wheels built will be the most expensive part of the proposition but not crazy expensive and I strongly recommend that you do it.
FWIW, I just built a commuter/touring bike and wanted a front disc brake becaues I'll be riding this bike in all weather conditions. I LOVE the front disc brake, riding in the rain or in the aftermath of rain when the roads are still wet is not a problem whatsoever and I love the smooth feel of the lever. I'm using Avid BB7 with 160mm rotor. great stopping power.
