As NAMoulton said, I would like to warn you (because you'll find 90% of folks on here will say it) that the Rockfather/Rocky Road lift is not a fan favorite. For a much more comfortable ride and dependable lifted suspension (and many will say better customer service), check out Jeepin' By Al or All J's for lift options. There are several good high quality full spring lift products that those guys carry:
1) OME (Old Man Emu) springs and shocks (it says 1.5 inches but you get 2.5 inches)
2) Ironman springs and shocks (2-2.5 inches)
3) JBA (Jeepin' By Al) Tommudd lift (an OME or Ironman setup with a few extra tricks to make it sit at 3.5 inches)
3) JBA (Jeepin' By Al) adjust-a-strut lift kit (more expensive but the cadillac of KJ/KK lift kits; 2.5 or 4 inches)
JBA also sells upper control arms (A arms) that make it easier to align your Jeep after lifting it. These are needed at 3+ inches and recommended at over 2+ inches of lift.

Google LostJeeps.com or JeepForum and Liberty with RRO or Rockfather and you'll find many threads with people's recommendations and experiences. It's good to read lots of them and ask lots of questions. You'll find many people are very happy with Ironman, OME, and JBA, having replaced their RRO or Daystar spacer lifts after not too long. Ironman, OME, and JBA all improve the ride and handling over the stock suspension, both on road and off.
As for bumpers, look up AtTheHelm. He's a welder who has some awesome designs for both front and rear KK bumpers, as well as some other steel goodies, like roof racks and tow points. You can PM him on here or on LostJeeps.com to place an order.

Rock Lizard Fabrications makes a KK front and rear bumper also, but they are discontinuing support for the KK at the end of August so if you want to go that route, you had better act fast. Some other folks have fabricated their own steel bumpers with good results.
