Okay, as far as paint peeling goes, it's the clear coat. It can actually be sanded, buffed then reapplied. To me, it's not worth it. If I were to do it over again, I would probably get the OE black chrome headlights (NOT the chrome/chrome), and retrofit those with the same HID kit and lens I used in the ANZO's. Also, LED light bar and my grill.
As far as involved, how involved do you want it to get? The ANZO's will work fine in their stock form so long as you don't exceed the 35W threshold. I went with 35W the first time, but went cheap. I loved those HID's but the ballasts were garbage, so eventually they failed. When I went back to halogen, I missed the intensity, opted for 55W instead of 35W and cooked the dishes. THAT is why I went with the retrofit kit, in order to replace my bad dishes.
If you do get the headlights, my suggestion would be to stick to 35W HID's with good ballasts in whatever temperature you want. I went with 6000k so it's as close to my LED light bar as possible. If you are doing the high beams, since they are separate on the ANZO's, make sure to get a fast ignite HID, if they are available to you. Since you have to wire up relay's for the LED light strip and halo's, I would also suggest putting any HID's on relays as well to draw straight from the battery, instead of the headlight harness. It made a pretty big difference for me, since I had a strange voltage droop to my passenger headlight. I stayed with halogen for my high beams, but never use them, since I'll just throw my light bar on instead. I get more usable light with it rather than my high beams in the ANZO's.
