Its really not that hard to do if you follow the manual, have basic tools and are somewhat mechanically inclined.
The front calibers DO have to come off first. **DO NOT SQUEEZE the ft or rear brake levers with the wheels off. Should that happen, the brake pistons extend out, you can push them back, but just don't touch the levers and save the headache.**
As for removing both wheels, put the bike on the center stand, break both ft and rear nuts loose (they should be around 87ft lbs). I would jack up the front with a small pice of 2x4 with a sizzor jack under the header (the front end is very light) and jack there, it won't hurt anything..
Both wheels will be off the ground for removal.
For any bushings/parts that come, you can have a piece of paper handy and write down where they go (ie: rt ft bushing, large end facing outwards, etc). It'll save guessing / mistakes later.
One quick tip, when removing each wheel, shim inbetween the floor and the bottom of the tire (I use 2x4's and thin plywood). The axle will pull out much easier without the weight of the wheel on it. Its also easier lining things up upon re-installation.
If your that unsure of your skills, do one wheel at a time or bring it to the shop... It NEEDS TO BE RE-ASSEMBLED CORRECTLY..
Good luck..
