Run springs. They aren't that expensive, and let you still have suspension travel. You are going to have issues with axle alignment even at at 2". You can use a relocation bracket at the rear and redrill the front, or use an adjustable track bar up front. I would never run a 3" spacer. Your stock arms will be okay if you don't wheel it hard.

Keep it level, there is no reason to raise the front higher than the rear.
