While I agree with bigbadswingdaddy, personally I wouldn't worry too much about changing the brakes over to disks. Since you already have new components in your stock system and you aren't towing anything too large, I'd say that the stock system will be ok for what you're doing. The real trick is to make certain that the adjustments are correct, fluid level is ok, and no air in the lines. You'll be suprized at how effective the stock system is when it's properly setup/maintained.
