Seeking Expert Advice on Modding 95 GT/vert

Well after searching through a lot of threads trying to find answers...yet I still haven't got the answers I'm looking.
I have a 95 GT/vert (automatic )with 24,000 miles on it. Looking to start modding for performance. So far I just put bassani x-pipe and flowmaster american thunder II on and a jet chip. I got a vortech supercharger on the way. What other mods would you recommend? I know a lot of people say heads, cam and intake...what are some good recommendations for those? Any good kits available? My dad was telling me I would need to run forged pistons if I start putting a lot of power to the car.

By adding the supercharger will I need to upgrade fuel efficiency too...better fuel pump or bigger injectors? or MAF?
A thought comes to mind as well...is it worth putting down that kind of cash on a stock motor though? by adding all new stuff. Is stock block, crank, and pistons good enough to take all the mods?

What I was planning on doing was getting 3:73 gears, bbk shortie headers and subframe connectors and maybe aluminum driveshaft. I have 255/35 yokohama sport tires which gives me great hookup. I'm not looking for a quarter mile car by no means...this is car I drive just in summer and like to play around with.
I'm looking for some good advice on what you would do in my position.

One last thing, is there a place you can find mechanics/shops, that are remotely close to you, who are mustang guru's that would do a good job installing and dynoing your car? I'd do it myself but I'd sure hate to mess up my car :biggrin:

Thanks for taking time to respond.
