Looking to do a 3" Lift, have a few questions.

EDIT: Accidentally double posted this. Mod can delete this, as it is more suited for suspension forum.

Looking at 3" lift and leveling. Was going to go ahead and get the lift out of the way before ordering wheels/tires.

Was looking at OME 885 pre-assembled on bilstein 5100's up front with an AAL pack for the back.

Truck is a 2013 DCSB OR.

1) What AAL should I be looking at if I want the truck level with 5100s@1.75 with the 885s
2) Should I go ahead and get the 886s if I plan on a heavier bumper down the road? If so, should I run the 5100s@.85 instead?
3) With the 885s giving 1.75 and the 5100s@1.75, that is 3.5" of lift in the front; will I be needing to do any other front end modifications to prevent issues? I've heard I'll need UCAs but I've also heard that I won't.
4) Am I going about this the wrong way? I've been researching all of this but it is my first time lifting a vehicle and I'd like to make sure it goes smoothly. My budget is rather tight at the moment, and I feel like this is my most cost-effective option at the moment, I just don't want it to cause problems.

Thanks a ton for the help guys.
