Which rear shocks for two stage lift?

Looking to lift my stock 2012 Access cab in a couple stages.

I've been looking at parts from Headstrong Offroad. I'd like to start the build with Bilstein 5100's and OME coils in the front and a 1" block and Bilstein shocks in the rear. Down the road I'd like to add the OME Dakar leaf pack in the rear and some UCA's in the front.

Will the Bilstein rear shocks work with a 1" block for now and an OME Dakar leaf pack later on? Standard length or extended?

Just looking for something to take me camping here in Colorado and Utah; I'm not looking to do serious rock crawling.

Thanks in advance.

 

Will the standard 5100's work well with the 1" block? May just skip the Dakars and
go with the block long term. Thinking I'd rather put the money saved into new tires.
Which springs in the front? OME883?
