Rear lift options

Alright, I'm doing some planning for what I was to do to my truck hopefully in the spring. I'm trying to find the best option for a rear setup. Im currently running a toytec AAL and front spacers. The lift adds about 2.5-3 inches of lift. The plan for the front suspension is to get some fox coilovers with maxtrac spindles; this will give me about 6-7 inches of lift with the toytec spacers in the front. Now I have a few questions.

1) I know that I am gonna go with a Dakar leaf pack which will give about 2.5 inches of lift. I want the front and back to be as level as they can. I know that you can buy the OME AAL to make it a 3.5. Now would my toytec AAL fit the OME instead of buying another $80 AAL?

2) I am now left with a 3.5 inch lift and I need to get it up to at least a 5-5.5 inch lift. I plan on using my truck a good bit off-road so using rear blocks is not an option. What would be the best method to lift the rear up another 2 inches or so?

 

Probably a custom pack from alcan, deaver, etc. Shackel flip, sua, all sorts off good stuff. For me, alcan would be my best bet!
