Suspension Help

I'll probably get sh** for not installing my ome lift myself but here goes. I'm purchasing an ome complete lift with front shocks (9000's), front coils (885's), rear shocks (n182's), aal 2" toytec standard, lr uca's, front top plate spacers for a full 3", trim packer, new center bolts and bushings with no diff drop, and considering sway bar removal or relocate. My question has two parts.

1. Will 885 coils support an all pro bumper or similar if I change in the future or do I have to have the spacers removed and 886's put in for that?

2. I've gotten some quotes from 700 dollars and it would take the guy a week to a 500 dollar quote and it would take a couple days. I'm waiting on one more quote from a guy I work with. Also fyi I haven't called any auto shops in fear the price for install would be outrageous. Am I being naive in not attempting this myself ? I have 3 ton jacks and all the tools at my disposal minus torque set wrenches and a compression spring tool. Ive heard you can rent them from auto zone for next to nothing. Need advice on the route to take. This is the only thing holding me back from pulling the trigger on the lift purchase.


Thanks in advance for any advice.
