I bought a 2001 Wrangler sport with a 4" suspension lift by superlift. It has 33 x 12.50 15 Toyo MT's with smitybuilt winch and front bumper. It also has some nice rock sliders. I was looking to get at least set of lockers for the rear possibly ARB so I can take them in and out.
you can also try forstec. they are pretty new but have spent hours on the phone with me making sure i get everything right the first time. then after everything was said in done he took $134 off the total ticket and sent me 3 free hats, shirts and a ton of decals. i will have pics posted soon. can't wait my mech. pushed my appointment to the 27th. man that sucks, but it is well worth the wait. going to make sure we have everything. the only thing i didn't get yet is my SYE. going to put in the transfer case drop till around may when i can afford the sye and axle.
Quadratec is a good place to start, but there are many other places too.
I'll probably get flamed for saying this, but I use 4 wheel parts a lot too. I notice that the same exact items are cheaper there and since I have local store about 7 miles from my house, I do store delivery and don't pay shipping.
