Nemos reef is awesome so is c-macsIf you ever go around Charlotte there is a lfs there called Nemos Reef that I absolutely love. I will drive from WV just to go to that store. Plus they list their current fish stock list online with prices so you can see what they have before going. They also have a list of corals online, but they way more corals than listed online.
How big is your tank? If it's a small tank that you could easily take all of the fish out of for treatment in the future then just hoping for the best probably isn't a big deal. If your tank is big and will eventually have a lot of fish then it is worth it to deal with the ich now and properly remove it to avoid problems in the future. With only two clownfish you could setup a quarantine tank for very cheap. I just started treating some of my fish with copper in qt for the first time and it seems like it's going to be easy to do. From now on all fish I buy will be going through a copper treatment before going into my tank (except for fish that don't handle copper well).
