You can do it without a lift -- I installed mine by myself with basic hand tools in my carport (concrete slab). I used Skyjacker Softride 2.5" front springs and have been very happy with them, and I have also heard very good things about Tuff Country. I didn't use the rear blocks but I have some pretty stout rear springs with AALs & overloads.

The only thing I had to change was the front shocks (I see the Summit kit comes with new shocks). Nothing else needed changing -- steering wheel stayed straight and brake lines are plenty long enough. For the record, stock rear shocks are the correct fit, the right length compressed and extended, to use on the front with 2" to 2.5" front springs.
