What kind of track use are you looking for. And how often is the main question.

The more expensive "name" brands are recommended if this is gonna be a track car. If this is going to be a street car that visits the track every now and then, then go with some brands the will save you some coin.

The track tends to beat on parts. So if you are gonna be there alot, buy parts that are internationally known for taking a beating.

If its just the streets, they arent that aggressive(DEPENDING ON WHAT PART OF TOWN YOU ARE FROM LOL)

I would suggest a coilover setup if you are track simply because of the tune-ability.
You can get away with a knock off flywheel if you are stock or basic upgrades. But they are cheap anyways so go name brand. While you are at it you will need a clutch. The ebay ones suck. NO

+1 on the bushings. They make a world of difference.

Motor mount kit for that car is cheap too. Ploy urethane will stiffin the chassis significantly.

Bring it by brotherz racing if you get some time. I can sitg down with you and we can discuss your goals. I could definatly help you out with parts sourcing as well.

Cheers!
