Trying to drive aggressively in a stock s13 seat is a pain. Hard to focus on being smooth when you're fighting to keep your body still.

AGREED. The MOST eye-opening upgrade I have ever made on my S13's was the first time I installed a race bucket seat. You don't really realize how much you're hanging on for dear life untill you don't have to do it anymore. A bucket seat is ABSOLUTELY NECESSARY if you're going to regularly attend track, drift, or autocross events.
As for the urethane bushings, the NRR guys are more critical than what is necessary. If you're not going to upgrade to full spherical bearings urethane is the only route. The main issue is keeping them lubricated. There are write-ups both here and on NRR for installing zerk fittings with your urethane bushings. Well-lubricated urethane bushings present NO binding issues WHATSOEVER. I've got full urethane (with zerk fittings) in the rear of my S13 with adjustable RUCA's and toe arms. With the shocks removed I can easily compress the suspension through it's full range of motion by hand.
NRR is a GREAT resource for 240sx enthusiasts who are more concerned with actual performance than style. I've been a member there for quite some time and there is TONS of technical information accessible there. Zilvia kids are not interested in anything that's not slammed and sliding into a wall at a high rate of speed. You do have to realize that a LOT of the NRR guys are at the polar opposite end of the spectrum though and reality is somewhere in the middle. Your car does not have to be a masterpiece of engineering perfection to perform well.
As for the FA coils, those are fine to start with. I don't think it's necessary to sell them and start all over. Concentrate on putting together a well rounded setup for the ENTIRE car and pursue your ideal setup from there. A Koni/GC setup using veilside180sx's housings would likely be a good upgrade in the future. There is a lengthy and detailed write-up here on that setup as well.
As stated, seat time is everything. Seat time with an instructor is what you REALLY need though. It is much wiser to spend your money on seat time than trinkets and knick-knacks to make the car "better". Start with the basic upgrades necessary for heavy track use. ALL maintenance items, GOOD brake pads/lines/fluid, TIRES, and cooling upgrades.
