Front and rear lift

Tacoma world suspension experts... I have a 2012 Sport extra cab and Ill soon be purchasing some 285/75/16 Cooper ST MAXX and Method 16x8 NV's as my stock dunflops are about done. While I'm at it I'm also going to do my front brakes and replace the stock pads and rotors with EBC sport rotors and yellow stuff pads. For a lift I'm going to go with 5100's front and rear and either Eibach or OME coils up front. If I use the 886 coils with the 5100's at zero should that net me 2.5 in of lift in the front?

I have an extra cab. If I'm planning on adding an ARB bumper and winch down the road will the Eibach 3in 620lb lift coils be enough or should I use the OME 886 coil? I want to keep my stock UCA's so 3in lift is probably out of the question. If I use the 886 coils with the billies at 0 will I still likely gain more than 2.5in up front?

If I'm lifting 2.5in in the front how much should I lift the rear? I'm thinking 1.5? I'm slowly putting together an overland expedition rig and estimate that between a rear bumper and drawer system, gear etc... I will be adding around 1k lbs to the bed of the truck. Would a 1.5in AAL be sufficient? I have the stock TSB leafs.

Thanks for any help! I've read a lot but I'm still trying to figure out what is best. If money was no factor I would be doing a lot more, however, alas money is a factor. Down the road I would like to do a full on setup with Kings all around, total chaos UCA's and Dakar rear springs but it's just not in the cards right now.
