its real easy, search for topics created by ECU-MAN. He did a DIY on it. Also, there is no need for a G-clamp, a screwdriver is sufficient enough to push the piston back. All you need is tools to undo the 2 bolts, a screwdriver and your brake pads. You should take some fluid out of the master cylinder aswell though (with a syringe), otherwise the shit will overflow everywhere. No need for bleeding the brakes, i didnt with mine.
Be sure to road test your car though. Just drive upto 60kms, then brake hard to a stop. Repeat this numerous times (id do it about 3-5). Also, after you install the brakes and put the wheels back on etc.. Be sure to press on the brake pedal a few times to bring the piston forward again, if you dont, when you first take off you will have no brakes. lol.
Just a few tips. Search for ECU-MAN's guide, i give it a 10/10. :D
If you can do all the things you mentioned, then a brake pad swap is a breeze.
I used anti-squeel and IMO, it does sweet f**k all. My brakes are squeeling even after using it, but you mayaswell give it a shot.
