HI, and welcome to the club. As to what you want, if you want fast, don't waste your time with a non turbo Eclipse. Definitly go right to the 4g63T. As far as between a Spyder and a GSX, if you are looking for a drag car that you will run up at Epping, NH, then you would definitly want a GSX. Not too mention AWD is great for the winter as well. However, if you want to be racing kids on the highway (not recommended of course!), then the FWD is definitly not a bad choice. Of course, there have been a number of people who have done AWD swaps on the Spyders, if you so desire. Hope this helps at all.
Just read up on everything, and of course feel free to ask questions. (NEDSM has a Newbie forum good for basic questions.)
