Want to get lifted need pointers...

Hey everybody. I got my Shrockworks bumper and slider on my '05 OR now I want the lift before I get new tires. I was thinking of REAR LIFT SHACKLES, LONGER BRAKE LINES AND FRONT SPRINGS from AC. The OR has Bilstien shocks as you all know. Now the questions: Anyone know what Bilstien shocks come with the OR/are they the same that AC sells in its '05-'06 Xterra suspension packages? If I need to change the shocks what size would you all recommend (12"-14"-17")? Do I need to get the two degree shims, if so where do they go? What would be better shackles or add a leaf, or can you do both? I was wanting to go to 285/75 16 tires but I read some people have problems with that size on the stock rim should I get them? If so, I have no problem staying with the 265/75 16 size. Also, is there a body lift? Would it be worth it? Yes when I shoot out questions I use my big guns lol. As you can see I'm not going too high and staying within a tight budget. As I figure around $300 for the basic parts I listed if I can use my shocks. I appreciate any help I can get on this or if anyone has a better set up let me know. THANKS!!!
