Looking for opinions on my 3rd gen

Hey guys, so I'm looking to see if any of you tech/ suspension guys have any advice or "what I would do" type of thing. So I bought a pro comp 3 inch lift, came with 4 pro runner shocks.

http://m.ebay.com/itm/161793469690?_trksid=p2141725.m3641.l6368 This is the lift I currently have. I'm running 285/75/16 cooper stt pros with the stock rim. I have stock upper ca's as well. The truck rides pretty rough because I just wanted to buy a cheap lift, put the tires I wanted, then upgrade after I saved some cash. So, to improve ride quality what can I do? Can I throw 5100s, new coils, and an add a leaf? If I do that will I still have the same amount of clearance for the tires? Basically for you were in my situation, what would you do first?
