06 Grand Cherokee WK Questions

I just started selling firewood and have a 5.7L Hemi with the 45RFE transmission. I am trying to get a little more out of my engine and transmission heres what i was thinking any ideas will be greatly appreciated....
I got the AirLift 1000 bags for sag in the rear suspension, but can i Also put on a 3.5 inch lift kit??
I have a transmission line pressure booster, cold air intake....
I saw on ebay there is a company that makes a turbo for $900 hard to believe and is it any good?
Should i got with a TransGo shift kit? Super Chips Programmer?
Any ideas are welcome, Thanks!

Your best option would be to regear to a lower ratio. The 545RFE has 2 overdrives, so you can throw 4.10s back there and not be screaming on the highway. If you plan on bigger tires and towing, go with 4.56s
