First Jeep JK Rig Build Questions (Simple)

Hey guys,
I'm a long time reader, first time poster because the day is nearing when I am purchasing my first JK and would like come creative input and criticism from you all if possible.

First a little about me and what my goal for my JK is.
I'm a huge mountain biker, snowboarder and enjoy camping, concerts and the outdoors. This will be first car out of college so I need to make a daily driver and wouldn't like to lose that much MPG with my build. I also have a good friend with a pretty solid garage set up that can accommodate all or most of that modifications I want to do.

My plan was to purchase the base model 2013 sport 6speed or find a used low mile 2013 or 2012 with under 6000 Miles. My search so far I would maybe only save between 1000-2500 dollars but would lose a year of warranty and acquire a slight lemon risk of the car.

What I want to initially do:

(1) WheelTireSet............................$2375 (5x475)
Body Lift 1.25 inch..........................$150
Body Lift Covers.............................$75
Jeep Hardtop.................................$995
WildBoar Roof Rack........................$1395
Mopar Trailer Hitch.........................$200
Miscellaneous Shipping...................$400
TOTAL .....................................$5590

(1)17 or 18 inch with a 4.5 inch backspace rims (Depending on price difference on tires) and between 33-35 inch tires and 12.5 inch width.

Questions I have:
First is it a good idea just to buy a sport and build?
Should I get the 3.73 gear ratio and anti spin diff options?
What size and type of tire should I get to increase offroad performance, but not loss a lot of MPG?
Is there any structural/mechanical differences between the sport and sahara?
Lastly will the dealership buy the new stock tires/rims?
Thanks in advance for any comment or suggestion given!

Yes get the 3.73 and I would look into a suspension lift and not a body.

Difference between a Sahara and Sport are the nice things like upgraded seats, stereo, trim and things like that.

Thanks Duckquacker! I chose to the Body Lift because I read that if its under 1.25 inch its not noticeable and a simple, cheap solution to add clearance for a larger tire

Body Lift in lieu of a suspension lift = loco. Here's why - the body lift is not going to increase the clearance of any of your suspension/frame parts. You would be much, much better served by a basic spacer lift or a leveling kit for basically the same price. Also, you don't need a lift at all to run 33" tires - and you can run 35" tires if you are willing to trim/replace your fenders.

As to tire - if it is bigger and heavier you ARE going to lose mileage. It's merely a question of how much. More mass and more rolling resistance (aka: bigger/wider tire) means more impact. It's what folks here like to call "pay to play."

Be aware that lifting your Jeep is going to decrease mileage slightly as well. As to tire choices - if you want minimal impact, get the 33s. The GY Duratrac is an extremely popular tire on this site for use as both a DD and trail tire. The Duratrac has a tread pattern that is considerably more aggressive than most AT tires and that helps bridge the gap between AT and MT. It's an excellent compromise. Otherwise, you can stick with almost any AT tire and look for the lighter options to cut down on the impact to your mileage.
