Im kind of stuck, need some suggestions

Its been a while since ive worked on my car. I dont have a whole lot of money but I am going to start to try to slowly (ie the new motor will be in in 2050 and its high performance parts will be laughed at).

This is for my 89 vert that is my daily driver. I DO NOT want to increase the power at all. I have a new motor built for the car, but its not ready for it yet. Let me list my very few list of mods. Mind you I only want things that will make the chassis a more stable platform for the power. I also love to corner. I am not really interested in drag racing as I still know people who can get me in with access to "customer" cars

So here is what I have done
that arenet in the sig

pro3i non adjustable lca(spherical/poly)
95 brake booster
MM full length sfc's
spal electric fan
battery relocation
pro 3i c/c plates
H&R lowering springs(i think they are the sports, but im not sure)
FRPP aluminum drive shaft

wow thats a short list

Things I know I want:
3.73's
Torque box reinforcing plates
im drawing a blank on the new shifter with the blue or red handle
mm panhard/torque arm
poly bushings up front
coil over up front maybe rear
Strut tower brace(probably gonna just fab this up)
sn95 brake conversion(im not sold on the rears yet)
probably a 6 pt roll bar


So.. if you were me what would you start saving up for next?
Any thoughts or suggestions on things I missed or things you would do differently?

yeah, a street machine that can corner. I dont really care about the 1/4. I think I am gonna get a shifter, then fab up my strut tower, then finich up the front suspension(bushingss and stuff). Oh and Hissin...Im thinking delring will probably drive me nuts... dunno tho. Anybody drive delrin on the street?
