WH mods, have your cheque book handy
1. Lift, the WH is to low & has probably sagged as well. There are kits from Old Man Emu, Dobson, EFS as well as springs from Kings & shocks from Bilstein. I have the CRDStu H/D lift (as I tow a van) and find it quite good for towing but a bit to firm in the rear for off-roading (no articulation).

If you are planning to go off-road I suggest a snorkel as the air intake sits directly behind the grill so there's another $500 + fitting

Tyre upgrade, you can go to 245/70/17 or 265/65/17 ( about 30") & still be legal on standard rims & the speedo should read spot on. You need to be careful though with 265's as they come very close to the top ball joint thread, the more aggressive sidewall the tyres has the more the chance of it rubbing.
A common wheel replacement that gives you more clearance with wider tyres are Commander rims. There is approximately 6mm less offset on them & it moves the tyre sidewall away from the ball joint bolt. With these rims you can fit 265/70/17 (about 31.5" to 32" depending on brand) tyres with minor rubbing on full lock depending on tyre choice.
I am running 245/75/17 (31.5") on the same rims as yours with minor rubbing.
You can pick them up at a bargain price from JK owners when they go bigger, just watch the for sale section
.
There aren't a whole lot of WH specific after market parts readily available in Aus, I think
http://www.murchisonproducts.com.au/...ue/WH-products support us the most so if you find something you want from the states give Stu a call & see what he can do.
GOBI make a nice roof rack in the states, I think "Double Black" might be an agent here in Au.

Anyway there's a start, I'm sure there will be more suggestion's & opinions on what is best.
Have fun
