Anyhoot, back to helping out the youngin'...
Best bet is to have a plan of attack, and stick to it. That's not always an easy thing to do, but it's the best way to accomplish goals. Make a list if you have to.
As mentioned:
Top 60k (plugs, wires, valve cover gaskets and plug well seals, check valve lash)
Front 60k (timing belt, water pump, crank sensor, cam sensor, cam seals, crank seal)
Rod bearings (rod bearing, oil pan gasket) Note-this is also a good time to replace the y-pipe with an aftermarket unit, if it's not already done. You'll need to pull the y-pipe to get the oil pan off, to get to the rod bearings anyway...
Now that it runs well, and most of the major maintenance is out of the way, you can turn your attention to where these cars respond the best: brakes and suspension.
Brakes: depending on your budget, and your plans for the car, there's lots of options. The stock front brakes are rather small, and while many owners have upgraded to the 11.6 front brakes from a 96-99 SHO, other owners have had good luck simply upgrading the pads on the stock brakes to a quality pad like Hawks or Porterfields. Main thing is, the stock front brakes with generic parts store pads suck. Upgrade something, and you'll be happy.
Suspension: At this point, there's not a ton of options left to replace your worn out struts and springs (assuming they haven't been done already). On a budget, I'd recommend either Intrax or B&G springs, along with Monroe Sensatrac struts. Plan on spending some money on sway bar bushings, end links, strut rod bushings, tie rod ends, lower control arms, etc. At the age of the car, if these items haven't been done yet, they're going to need it. Better to save up, and buy all the things you need, before you start tearing into it.
After all of this junk is done, you can start playing around with it to fit your needs. SHOSource.com is an excellent place to get the parts you need, as well as
www.rockauto.com for stock replacement parts. Don't forget to check the classifieds here as well.
Welcome, and good luck with your first SHO!
PS, as tempting as it may be at 17, forget about clutch dumps and massive burnouts. The differentials in these cars don't take kindly to stuff like that.
