It's almost as easy as changing spark plugs, but will cause even more damage to you and the bike if you do it wrong. I advise getting a manual. Suzuki used to make great shop manuals, but I don't know if they still do.
If you haven't gotten pads yet, get DP (Dunlopads) HH pads or EBC HH pads. My CBR uses guide pins and I always replace them. Just remember how the anti-squeel shims go, if yours has them, and keep your greasy mitts off the working side of the pads. I also clean the rotors with some 400-grit wet n dry sandpaper.
