Congrats on the new truck. /forums/images/graemlins/waytogo.gif
We try our best never to refer to them as 'cars' here, or 'SUV's' for that matter.
I have a Jimmy too, and even after 7 and a half years the name still sounds silly to me. I usually call it a K5 or 'my truck' and have even occassionally referred to it as a Blazer (Chevy envy? /forums/images/graemlins/whistling.gif)
Anyways, a good all around suspension set-up would be a shackle flip in the rear and some Tuff-Country 4" springs up front. The shackle flip in the rear allows you to keep the factory rear springs you already have, while getting rid of the blocks. You will likely have to adjust the pinion angle and drop the back of the t-case/tranny an inch or so to get rid of driveline vibes though.
I'd recomend a bit of research before you break out the credit card and start ordering stuff though, the devil is in the details...
The difference between a truck that works really well and one that doesn't isn't usually a lot. The details make all the difference, right down to shock length and even tips and tricks to maximizing the rest of what you have.
Take the time also to examine the frame around your steering box for any signs of cracking. The 73-91 GM truck frames are notorious for fatiguing the frame around the steering box. There are repair kits and aftermarket brace kits for that if you do find anything...
