I put a baby stall on my DD Z28. It helps alot. I went small so I wouldn't be driving around with it unlocked all the time. (I'm usually in the 2400-2500 range around town)

Next on the list is LT's, new catback, 1.6 rr's, and a tune.

Im keeping an eye out for a set of used ceramic coated headers, either shorts or mids. Does anyone know if the 93s require a certain type of headers, I know some things are slightly different on them than the 94-97s.

Like I said earlier the roads are just too bad around here to have LTs and and not get them all banged up.

Get stainless steel headers. They can still be ceramic coated if you like, but mild steel on a daily driver is a mistake whether it's coated or not.

Also, note that the more expensive headers (like Kooks) have equal-length primaries, which both sounds better and makes more power than cheap headers (like Pacesetters).

Where is the best place to get stainless headers? I tried to search for Kooks and nothing came up for my 95 LT1. Since I am going to replace my head gaskets soon I am planning on putting headers on it.

Would ideally like to get stainless equal length headers.

So, I have the GU2. (probably why my car is a dog) I have to change the entire rear-end. What is the best to get? Which car is most likely to have it?

No, you can just change the gears inside it.

You'll most likely need to upgrade from your 2-series carrier to a 3-series carrier as well.

look in the glove box there will be a white stick read the code if u have GU2=2.73 and GU5=3.23 also if you car doesn't have the first gear in the automatic shifter also means that you don't have the performance rear end which is 2.73.
