Sounds awesome.
on the bigger altanator look at Power Master! For starters too.
Dual battery is pretty easy take a look at my photos. Ranger makes the set up I have.
Are you going to regear it to a lower gear(s)?
How about a hitch mounted winch and a hidden hitch upfront? ( to mount which up front, or in the rear that way)
VHT makes a candy paint / tint that's what I used on my wife's Tahoe's Taillights great choice. Although you can't go wrong with LED.
Road arrmor makes a trailer hitch mount for oversize spare tire and wheel and you can mount a fuel can to it also.
The power inverter is a easy mod to wire up and a lot have remote USB ports ! ( I picked one up from Pepboys)
What else do you plan on doing?
What about a Wilson mobile wireless dual-band signal booster?
CB?
Air helper bags in rear coil springs ?
Putco makes vehicle specific LED interior lights I have them and love them.
Led bulbs for turn stop Tail and parking ?
HIDs I always use DDM tunning
Are you going to have a third row? If not and you don't need a bench in the back seat. I'd do a rear cargo box. Check police auctions ! And swap middle seats to bucket seats and put a second center console in the middle and mount a cooler inside it.
Power wise have you thought about wiring up solor panel(s) to trickle charge the battery(s)?
Also roof wise what about a Yakmaa rack?
HD hood? ( has more of the NNBS hood body lines and looks really stout!
I would mount an E-tool and and off road jack too and some water and a fire extingersher flash light ( stream light stinger) and charger.
Maybe some N-fab hoop steps I know you said get rid of your steps but it's some side body protection.
