rear diff gone!
so the thing finally called it quits. im looking to replace it my self with better gearing. my car is daily driven so i dont want anything to crazy (i dont want to be cruising at 70mph and be at 7500rpm) im also looking to talk to some people that have done it themselves and see what im getting into and what gears they used.
if anyone can help with knowledge on the subject: pricing, company's, good gear ratio's, etc. i would greatly appreciate it.

Lots of good information in the thread. A DIY on a gear swap can be done but, be sure you have someone that knows what they are doing to help you out.
Good luck

also...my diff case is fine. if i were to rebuild my diff using that case but with after market gearing would that make the diff stronger than stock because of the gears or would it have the same "strength"
let him make it for you

Wait so what failed ?
What is wrong with the diff you have now. It may need only a simple adjustment to be right again.Any diff from 00 to 03 is plug and play for your year car.

Any S2000 diff will work on your car. As puddy said the 00-03's are a direct swap. The newer diffs would just require you to swap the input shaft from your current diff to the new diff. If you come across an 04+ diff, they are supposed to be a bit stronger.
Swapping the differentail is very straitforward and simple. It is a bit of a pain to get the new diff mounted into place, you'll definitely want to have another person to help you with that. Actually building and setting up the diff is a bit of an art and easy to mess up so you probably don't want to mess with that.
Going with a different gear ratio in an S2000 is highly overrated, IMO. The 4.10s are aggressive enough that there really isn't much performance to be had from switching them out. On the other hand, I actually got slightly better gas mileage with 4.44's than I did with stock 4.10's. If you find a deal on a differential that's already got gears I would jump on it, but if you're going to buy the gearset and have it assembled it's just not worth the extra money, IMO. If you run the 4.57's they ring gear is supposed to be significantly stronger than stock. Unfortunately that does not seem to be the weakpoint in a stock diff anyway so it really isn't much benefit. The caps and pinion seem to be much more likely to let go.
Good luck, let us know how it goes.
