Welcome
The CCM 2.5/1.0 kit is probably the most popular level on this site and gets lots of praise. From the pictures and threads I've read it delivers a true level stance. I used a 2.5/1.5 level to maintain a slight amount of rake while getting the extra clearance for 33's.
It was slightly more expensive: Truxxx 2.5" adjustable front level ($170) and a rear coil spacer/shock extension kit off ebay ($68) havent had issues with either
Some people don't trust shock extension, and probably for good reason, I have done some intermediate off-roading without issue.
You will probably still want to do some minor trimming to the front of the wheels liners even with the 2.5" front kit
The Airaid Jr intake also gets a lot of praise, I believe Black Bear posted test results showing it to be the most effective of several aftermarket intakes. I would recommend the dry synthamax filter if you go with airaid.
I have heard that a TB spacer is pointless for these vehicles, though i believe some have used them in conjunction with an aftermarket intake.
Maybe look into a catch can, there is a few recent threads about them, just installed one myself, trap that nasty crankcase oil vapor from gunking up ur engine
