New Owner Needs Insight

Hello all, I've been lurking for the last few months taking in all the info I can. Well I got a '15 SR5 DCLB MGM and I wanted to do the whole shebang to her (Icon lift, full armor, racks, lights, tent, Full Expo Style) then the dream was over. Like most this id my DD so my realization has led me to want the following.

17" Wheels with 275/70 tires
Mild lift (2")
Sliders
Avid Bumper protectors
Hidden Bumper winch
Bed Cap
Weahertech Window Visors
and stereo upgrades holy crap does our stereos suck!!!

Anyways to my question I've narrowed down my suspension to Billies all around should I go with 884's or 885's. I dont want to get UCAs at this time. Just dont know what spring to get with the possibility of the future winch. Also will a 1.5" AAL be fine? I've read a ton of threads just can determine what would be right. I just want a little bump over stock also not looking for level I do like the look of rake and it is a truck after all. All thoughts appreciated!
