xpro, I'm going to make a couple assumtions here: you have four wheel drums and suspension components that are original or old enough to need replacment. I'm also going to asume you can do the majority of the work yourself.
I would start with a complete front end rebuild. You can buy a kit from places like performance suspension or you could purchase the parts from a local parts store (Advance Auto parts in your area?) They carry TRW suspension parts. TRW is owned by Federal Mogul which also owns Moog but for some reason the TRW stuff is generally cheaper. Check www.advance-auto.com
Anyway, you'll need upper and lower ball joints, upper and lower a-arm bushings, inner and outer tie rods pitman and idler arms. I think you'll come in at around $250-$350 for the parts plus labor to install the ball joints/a-arm bushings and an alingment. (that figure is just a guess though)
The next thing to consider is the condition of the tires. If they need replaced that is what I would spend the rest of the money on. The drum brakes can be made to work reasonably well for a daily driver. You can then save for a disc upgrade down the road.
If the tires are fine, then a disc upgrade would be next on my list. Do a search on disc brake swaps and the "cheap big brake" swap in the archives and determine which route is best for you. I've seen figures of around $500-$600 posted in the past for factory style discs-probably requires some digging through the junkyards. David Pozzi has a list of donor cars on his web page.
After all that, if you've got a little $ left I'd consider the Competition Engineering solid body mounts. They're available through Jeg's for $40 or so.
As stated above, get a plan and stick to it. Write out a list of everything you'd need and do some comparison shopping before you buy anyhting and don't forget the little things like chassis grease, wheel bearings and seals if needed etc. If you mail order anything, see if you can find a majority of what you need through one place to save on shipping charges. I really think $1000 to $1200 can go a long way if you're careful. Tires can eat a big amount of you budget but hopefully you won't need them. Good luck!
I just went to Advance Auto's web site and filled my "basket" with all the suspension parts for $224 and change......
I also meant to mention that for a little more money you can get poly a-arm bushings rather than rubber
