Ceramic pads if you want them to last longer, semi metallics for the best emergency braking. Check out summit racing for some brands like Hawk, EBC, etc
Rotors are a cinch to change once the calipers are off unless you live in the rust belt. Depending on year, may need a 3/8 hex (allen) socket to get caliper off, or a TORX bit like my 2005. Shouldn't be air in the lines unless you change the brake lines or calipers. Still a good idea to change the fluid since its hygroscopic. A helper is nice to bleed the breaks.
Rears can be a little longer if it has disks, b/c of the drum in hat for the parking brake. If just drums on the back, they can take a while to back off the adjusters if you've never done it or turn it the wrong way.
If this is your dd, best to do it on a weekend if you havn't done it before. Could also practice at one of the local pick a parts.
