For one thousand dollars I would get new brakes, new tires,new serpentine belt, oil change, new battery, gallon of coolant, and some car wax...just to make sure it runs nice now.
But that is just me.

ok this is a hard question to ask- but how much of a performance gain do u think i can get by chaning the gears, and also new exhaust system? would i need to go to a d44? and would it offset my speedometer? -
o and how bad would that decrease my mpg and top speed? not that top speed maters

"I would say yes, you've got the 2.73s. And replacing them with 3.54 or 3.73 gears is something best left to a pro. Having it done correctly will likely eat up most of that $1000..."
I thought lt1's without G92 had 2.59 that is if it's auto which I think I read where he said it was. My 95 has g92 g44 option it has the 3.07's...all I've saw in person without htis option had 2.59's.

Performance gain and mpg are determinate on the gears you go to and your driving habits. If I remember from past posts, 1/4 mile time could go down by up to .5 and your mpg average could go down by 3-4.
As stated earlier in this thread, you're not going to feel much with just exhaust modifications short of headers and as for a Dana 44, as long as your engine stays basicly stock and you stay away 3.x gears and drag radials, I don't think it's necessary....

"Yup, you're right about 2.59s. So was I in my earlier reply in this thread but I wasn't paying attention and missed him saying 2.73... "
Ok, yeah when I read about it having 2.73's I was thinking wow I learn something everyday in here haha.
anyway Reed if you have 2.59' I would upgrade to 3.07's if it is a daily driver that might see track time like at most 5 trips to tha track a year...anymore than that you might want to go with the 3.54's.

You could go to 3.07s but that means you'll need the entire carrier as well as the ring and pinion gears (because you have a 2 series carrier in your Dana 36). If that's the route you want to go, you're better off bying the whole 3.07 Dana 36 pumpkin from someone who is upgrading to a Dana 44. They can be had for $300-400 dollars and swapping out your old one IS something you might be able to do...

I gave 8k for it (w/ both tops)
Actually exhaust is probably the best place to start. Every other mod on the intake side won't see any benefit until you match the rest of the intake system.

I think you already have a 13 second car myself... 
Tune it up... a real one... and be thourough.
And a good set of headers... your car has em on the market.
But that tall rearend can be brought down a notch or two, as long as you don't put 500lbs of torque through it to hard... then you'll need to change up to a 44... (but I still haven't broken one of em myself)

The speedometer can be corrected through the drive and driven gear and sensor change. I believe it was about $35.00. The only documented gear change that I know of that would apply to your situation was done by a member, NickD, He had a 94, and went form the 2.59 gears to 3.54 and picked up .5 seconds and 4mph.
The next step is to increase the stall of the torque converter. This will put you into the 12's on a good day. When mine was stock, except for the gears (3.54 at that time) I ran a best of 13.17. With the addition of a 3000 stall yank converter, I ran a 12.91 and both of these runs were done on mich. street pilot tires. (not drag tires)
The next thing IMO would be the roller rockers. Member, 96 redcoupe, documented (recalling from memory) .2tenth of a gain with 1.6 roller rockers and new springs.
The exhaust is something to do to change the sound. For the dollar it is not the best investment on a LT1 performance wise.
Again, Nickd tried the shorty headers and picked up nothing in the quarter mile.
The exhaust is already a low restriction system on the LT1 (according to the factory sales brochure)
Of all the mods I have done to mine I have enjoyed the gears the most.
So my vote is for gears.

as I stated in an earlier post here, at the mileage you are currently at, find out if the opti has been replaced and if not replace the damned thing.
you can do all the fancy crap you want, but if the opti is junk, so will your engine be.
replace the waterpump, too.

love my 373 gears,think the magnaflows lost torque (butt dyno) but sound neat.
at w.o.t. with 373 gears mine shifts out of 3rd to o.d. at 115 mph (still pulling in 3rd at the traps im sure)
for cruising 3k rpms in o.d. is 90 mph,1800 to 2k range is 60 mph.i get 21 mpg average (bout 3 under most other 92 autos w stock gears)
just dont put sticky drag radials on there and you should be fine.if it pops then go to a 44. what else ya gonna do with the 36? they dont bring much for cash anyway
have fun and welcome
