TechnoToyTuning is great. They had a great program (I'm not sure if they are still running it) where you could send them suspension components, cam gears and shifter assemblies and they would give you store credit for them. You should call them up and see if they are still doing that.

The 20v swap is a great thing and most address the distributor issue by just going with an aftermarket ECU system which deletes the distributor.

As far as the suspension goes, I would make the effort to replace all the bushings in the car before you do anything. You can go with either new OEM bushings, TRD (hard as hell to find) or urethane. Those make a big difference.
