If you want to really do it cheap and easy get some extra stock leaf packs to add to the rear springs and a set of rears up front with and extral leaf or so with a re-drilled center pin hole so they work with the stock steering. I used these with longer shackles and a set of longer shocks and the results are pretty good. More travel, better ride quality and very inexpensive. You can net about a 2-2.5" lift, maybe more if you do the j-ball flip on your steering. With a little triming and hammering on the firewall seams you should be able to run 35s.
As stated above, cheap lift springs really suck.
