Did you follow the article on this website about treating ich? Good read...
Make sure that your tank is ich free for a week or two before adding more fish. Not really neccessary, but since the fish aren't allready in there, better safe then sorry, no?
After your tank is definantly ich free (no spots at all for a good period of time!), then go ahead and add some fish. I'm sure there are articles around here on acclimating fish, and since I've started doing it VERY SLOWLY and carefully, I've had much better luck with new livestock. It took me a long time to develop the patience, and I had a lot of dead fish to show for it :/
How long has your tank been "cycling"? It can take 4 or 5 weeks to get done properly, and when you're new you probably overfeed which makes the problem worse. The ammonia kit I have is almost clear at 0 ammonia and gets yellow at higher readings... are you reading the kit properly? And I know it's a pain, but check the nitrites as well!
Finally, as someone said, finding a different fish store could help. I don't think I've ever had a petsmart fish live past 3 days... but I haven't bought from them in a long time, so it could have been my fault
If you got ich from the fish store you're currently using, they could have a problem!
