Need help picking springs for YJ suspension conversion

I'm about to do the YJ suspension upgrade on my '83 CJ-7.
I have the adapter kit from Quadratec for the shackles, hangers, etc. and now I need to choose springs and shocks.

I want to run 31" tires, and maybe have the room to move up to 33" if I want to later on.

Driving will be mostly on the street and highway, with some off road here and there, especially during hunting season. I live in the Mississippi Delta region, so that means mud, not rocks.

Here's what I think I need to know:

1. I've heard that just changing over would give an inch or so lift, even using stock Wrangler springs. Given that, what "lift" would I want to specify when buying springs? If I buy 2.5" springs, for example, will that result in 3.5" lift overall?

It appears that Rubicon Express and Old Man Emu are big favorites around here. Would that hold true for a dual-use driver like mine?
Recommendations?

2. Once I've figured out the first problem, how do I choose appropriate shocks? I have had good luck with Bilsteins in the past, but that was on sports cars. How are they for off-road/dual-use applications such as Jeeps? Would it be better to match up a set of OME springs and shocks?

Comments and suggestions, especially those based on experience, will be much appreciated. Ditto for the things I might not be taking into account.

I knew it would be out there somewhere. In fact, I did a search but for every combination of search terms I used there were way, way too many pages of hits to ever wade through.
But I figured if I posted this, someone would point the way to the main threads - and I thank you for doing so.

No problem,

I have found that if you just go to google, its way easier, and it will show the jeepforum results
