How much extra product do I need to have saltwater instead of freshwater? Can I simply use the freshwater pumps, heaters, etc.?
Do regular aquariums work for saltwater? I know that in the stores the saltwater tanks all have some different looking features to them as far as their setup and suppport systems.
Are the freshwater acccessories such as plants and rock okay?
Also, how are the prices for fish? I know they are a little more pricey, but what would I be looking at to have a nice full 65 gallon aquarium? And along those lines, do you need a quarantine tank?
Any help would be much appreciated.

Heaters can work, but a good saltwater tank is going to need quite a bit more water flow to keep the algae down. And no, you don't want to use the plants and rock because it is unlikely to be a healthy setup.
A healthy saltwater tank needs to have a great deal of live rock (porous rock) to allow bacteria, etc... to grow and certain types of algae for most attractive reef fish to graze on. If you don't have good water flow, that algae will get a little out of hand (as will things like cyanobacteria).
Freshwater can be done pretty well with a couple of Penguin bio-wheel pumps and little else. For saltwater you're going to probably want a sump setup to allow for plenty of water movement and a haven for bacteria. You'll
definitely need a protein skimmer as well; it's the most critical element of a decent saltwater setup.
Oh, and the light is absolutely critical in a saltwater setup whereas I never noticed a huge difference with my cichlid tanks.
A slightly cheaper marine setup would be a FOWLR setup (fish only with live rock). You don't need the high intensity lights because you aren't growing corals. You can have some of the larger angel-fish and more predatory fish like puffers, etc..., but you can't have most of those little reef fish that look so pretty in the fish store. And ultimately the reef tanks are just more attractive than the FOWLR setups.
Your question is a little too broad to give you the best advise, but ultimately I wouldn't use any of the rock from a freshwater setup because it's not going to be porous enough to act as good seed rock. Frankly, you'll want to go to a store and buy 'live rock' first anyway...lots of it; in a 65 gallon tank I'd go with about 100 lbs of live rock and a deep sand bottom. Alternatively, get 10 lbs of live rock and 90 lbs of good, porous seed rock and the seed rock will eventually go 'live' when the critters living in the live rock move in. Don't use the plants because they look tacky in a marine aquarium, IMO. But hey, that's ultimately your call.
The fish are much more expensive. A 'cheap' saltwater fish that's not an evil-ass damsel is going to cost you $20; something like a Royal Gramma or a clown (though a clown
is a damsel, so realize that it might turn into an asshole). A 'normal' priced fish like a Coral Beauty or a Foxface would be in the 30-40 range. A mid-range fish like nice hippo or Kole tang would be 40-60. The most I've ever spent on a fish was $80 on a big Naso and about the same on a tiny little mystery wrasse when they were damn expensive.
Something like a Hawaiin black tang or an achilles tang can run you in the $300+ range. At 65 gallons, they aren't a good idea.
A saltwater tank requires some homework that a freshwater doesn't. You need to know more about how big the fish will get because they're much more likely to outgrow the tank. They are more prone to stress-related diseases if you don't have a decent sized tank as well.
If you want to go saltwater, do it right. I wouldn't recommend anything less than a 90 and ultimately I think a 125 or better is the way to go because that's when you get to the 6 foot wide tanks that give ample swimming room. Moreover, the more tank volume you have, the less prone the tank is to spikes in levels and therefore the more healthy it is.
