The 10 bolt has a 7.5" ring gear (for your year IIRC) where as the 9 bolt has a 7.75" ring gear, both are puny. My 10 bolt has a 9.75" ring gear but I wont get into that.

Buying any quality car part costs a lot of money, a quality used 12 bolt will always be upwards of $1000 like you said, or over 2 new, same with a 9", etc. I would advise to save up some money and put some quality pieces under the car so that when you build a healthy engine the rest of the car can already handle it. It will save you money in the long run, instead of fixing broken stuff (rear, trans, etc) repeatedly.

Good call on the suspension stuff, but just know that doing more things to make the car hook will inevitably end your rears life faster.
