Grab yourself several cans of brake cleaner as well. I prefer the cheaper, more flammable stuff, as I, like many teens, was a pyromaniac back then.
A floor jack and two jackstands (*not* the recalled Harbor Freight ones everyone's dumping right now) will get and keep the front or rear of your vehicle off the ground while you're working. Wheel chocks don't hurt, either; if you can't find any, just use several two-by-fours.
You'll need a pad-spreading tool before you insert the new pads and place the caliper back on its mount.
If you don't yet have a torque wrench (3/8"-dr, 1/2"-dr), I'd get one. It's easy to be over-zealous tightening things when you're new to this.
When you're finished, regardless of what anyone says, find a stretch of empty road and go through the burnishing process.
