I'd take it to a track day or two stock and see how you like it before dumping $5K into it. Plus that way you can kind of calibrate your mind for what the car is like stock and use that as a benchmark for comparing future improvements to.

For $5K you can do a lot:

Coilovers
Front and rear sway bars
Extra set of wheels with sticky tires

I'd personally go for something like this:

Bilstein PSS9 or KW V3 coilovers - $1,800
GT3 front sway bar with end links - $450
Tarret rear sway bar with end links - $425
Wheels - $1,000 used
Tires - $1,200 or so

I think that would be a pretty slick setup for the track, and on the street you can throw on your street wheels/tires and simply adjust the shocks to make it softer.
