My suggestions when doing it yourself are these - do not use shock extensions. Buy replacement shocks...there are several budget friendly shocks out there that are of good quality (TeraFlex and BDS are my two favorite inexpensive shocks).
When removing the shocks, if the nut on the post of the front shocks (upper) is seized up, channel your inner anger, and crank up and down on the shock body. The stock shock will snap pretty easily, and save you a lot of time and headache.
Don't remove your track bar. You don't need to, and will decrease the odds of developing "death wobble" by avoiding doing so.
Two 18mm wrenches, two 16mm wrenches, and one 15mm wrench is all you need. Oh and a 10mm wrench can disconnect the brake line bracket from the frame and give you plenty of slack, if youre worried. And a 19mm socket and ratchet with a 3" extension for removing the tires. And a set of jack stands and a jack.
If you don't have tools, now is great time to buy two sets of metric wrenches up to 21mm (one ratcheting 12 point set and one 6 point set). All of that plus the jack and stands will be about what you would pay in labor, and you're setting yourself up for future odd jobs
