You really only need one c-clamp. Just use the removed pad as a bridge. Screwdriver is helpful as is a 10mm (?) to bleed the brakes. It's not a bad job, and for what you would pay someone else you can use brand new parts (loaded calipers included). It's just basic tools, pads, fluid, anti-squeel goo (<--the technical name ), and some time...go for it. Napa should have everything you need and the job should cost well under $200 with just new pads (front and rear), $250-$300 with new rotors and pads (no drums as they are usually within spec, the fronts are the ones that take the beating). If you really want to get crazy, damn near the whole system can be had for $800 or so...
