If you don't already have the fish, I think getting it right now might just be a bad idea, just wait until you get all your other issues cleared up and then try.
But to answer the question, if the fish was just delivered to your LFS, and now you're putting it in your own tank, yes you should wait to treat it with anything. Make sure it's eating and continues to eat for at least a few days. Then, if you choose to hypo right away, that's your call but if done right, you would certainly stop ich dead in it's tracks right there.
Also, there have been a few, more experienced, people on the boards that have said copper isn't good to use with tangs because their digestive system is more sensitive to it, so I'd just stick with hypo.
