Help me figure out what I need please.

Ok guys,
I've researched and am confused and just need some simple answers. I've got a 1972 c20 suburban that is currently stock height, and originally had a big block in it. It is a daily driver. I installed a l92/6l80e combo (so it's lighter than the original big block combo). I would like to lower about 2" in front, about 3" in back. My wheels stick out a little so I really don't want to go much lower, and I still want to be able to tow. I have an airbag setup I planned on using in the rear(coil spring rear), and keeping coils up front. I planned on cutting one coil off of the front. I don't really want to change out spindles. But since the truck was originally a big block, would I be better served with different front springs? Especially with the lighter engine/trans combo?
Also, I was interested in using Monroe shocks, not necessarily lowered shocks specifically. With my minimal lowering could I use stock height shocks? If so, does the regular vs heavy duty shock make much of a difference in ride quality?

I know this horse has been beaten to death, resurrected, and beaten again. But I have researched and researched and am now more confused than ever.
Thanks in advance for your help!
