and where is the best place to buy parts?

I love my SRI but I only get the sexy noises at wide open throttle. Get a header from eBay so you can hear the sexy noises all throughout. As for muffler... don't buy anything from Pep Boys, Autozone, etc. Ask some members how they like their mufflers and what kind of tone they have before you make a choice. You don't wanna end up with a rattling bee on crack.

how hard is it to install a new header and muffler?

for the first thing, I would just get a short ram intake, or a cold air intake you can ebay them for very cheap (no super power gains) but they are cheap, look cool, and give your car a nice sound when revvvving

ok cool.....I am looking to make the car louder cause its very quiet

I dunno how easy it is to install a header on a GT, since you have to jump through hoops and fire just to put one on an ST. But if there's no need to extend the header, then it should just bolt right one. And muffler.. if you get a catback, it might be easier to just take it to a muffler shop. They'll do it professionally for SUPER cheap.
