A set of slotted rotors (zinc coated) and ceramic pads are pretty good. No need to upgrade calipers. Install is easy. Take the wheels off and each caliper is held on by 2 bolts (13mm I believe). Front caliper pistons simply press in but for the rears twist in so you'll need a caliper compression kit (I got one for $20 at Harbor Freight with multiple attachments) or the cube tool which is like $8. Caliper brackets have to come off and each one is only held on by 2 bolts. Pull those off then the rotors will slide right off so you can slide the new ones on. Bolt the caliper brackets back on, put a little brake grease on any part of the pads that touch metal, put the pads in, put the calipers on, bolt down the calipers, install the wheels, take the car off the jack stands, torque down the lug nuts, and go test out the new pads/rotors. Sometimes taking the cap off the master cylinder helps makes the calipers a little easier to compress.
