Not running a Cobra, but have coil-overs all around (see sig).
I figure you are considering poly all around on your IRS? I have only 3 poly joints on my ride (one end of PHB and at axle-end of rear LCA's) and the rest are Heim joints. You will get considerable more road noise going stiffer bushings, but achieve better steering response and cornering.
I am sure this does not completely answer your question, but will give you an idea of what to expect.

I started doing stuff on my 98.It was bone stock. The front end would drop about 10 ft in heavy braking and had bad body roll. First I did a pro kit suspension from eibach this was way better.Its was springs and struts/shocks. Then I did The rear lower control arm MM. And a MM pan hard bar. Made is even better. Yesterday I installed new front sway bar bushings and aluminum steering rack bushings. Next i will do front control arms and steering shaft. Just goofin with this car. Fun to install this stuff now that I have a 2 post lift

The nose-dive under braking is best corrected by re-location of control arms via "K" member and tubular arms. The LCA's up front are moved rear-ward and the tubular arms are swept forward to re-center the wheels. This changes the pivot relative to the front axle and greatly reduces the brake diving. Coil-overs work well as movement from spring and shock are on same path, but not the overall best mod of suspension work I had done. The biggest improvement on my car came from the body support via "K" member and upper/lower sub-frame connectors. Once you have a solid frame, you will get the most out of ANY suspension mod. This will also help you get the most of your HP as well. My car is EXTREMELY responsive on the road and a complete rush to drive

EDIT: quite the list of rides you got there

I will be doing alot of work on my 03 in the next few months. I would really like that car to stick to the ground. It looks like new and only has 16k mile on it. I will be posting pictures asking what others have done. I just started dicking with the 98 cause its not a irs and a little older
