I just purchased a teraflex 4 inch with hydrolic bump stops, 8 adjustable controls arms, brake line extensions, exhaust spacers, falcon 3.1 shocks and I got a high angle cv joint kit.
My question is, is there anything else I need as to avoid any damage or excessive wear. Or just any suggested parts.

 

It came with a front adjustable trackbar and rear trackbar bracket? Do some reading on draglink flips/high-steers. Not must-have, but at that height a lot of people opt for one.

 

 

Common sense goes a long ways to avoiding damage.

You're probably going to be addressing all steering components along the way. Plan on a tie rod and ball joints. High steer kit as mentioned above may be worth a look for you. There's always something...... One of the biggest mistakes people make is buying a lift kit and thinking they're good to go, nothing more needed. If you're going to wheel, address all recovery gear as well.

What size tires are you running. Rear axle shaft flanges bend pretty easily.

 

I'm keeping 17s but I'm putting 35s on it and I don't do much real wheeling mostly bumpy trails and small hills. It's my daily driver. My xj is the beeter

 

Sounds like you've hit the major issues then. You should have correct caster with those adjustable arms, and addressed the DS. Higher steer kit probably worthwhile. Factory TR could last a while if you're not wheelin much. Do keep an eye on and plan for ball joints at some point though. 35s+ tend to eat those up.
