The following is my opinion and is based on owning several of these types of trucks over the years.
Any and all suspension parts(ball joints, tie rod ends, idler arm, ect) MOOG is the best hands down. Speaking of that....make sure and check your idler arm and ball joints as they have chronic wear issues.
Brake pads- I would stay away from the super hard ceramic pads as they can eat up your disc and also can be noisy and sensitive to dust and moisture. I use Car-quest Gold line as my son works at Car-quest
IMHO, if you can afford it I would replace the caliper as well. If they have never been done then there is a good chance that when you squeeze them open to replace the pads it will scar the inside of the piston and that will cause a problem in the future.
Shock- Bilstien hands down the best, period! expensive but they will give a real world noticeable difference and have lifetime warranty. The only exception to this is that you might want to go with a coil over shock to help with the typical chevy SUV butt-sag.
Check the seals in the rear drums, these can start leaking over years and cause your rear pads to deteriorate.
Hope this helps!
Good luck!
