I don't know the specifics of your state, but here is some general info. One typically needs to register with the state and perhaps municipality to get a Tas ID certificate. That puts you in their system to collect and pay taxes. What you have to pay tax on is a function of your state. It might be just prints, but it could include sitting fees and other services. A resale certificate enables you to buy things that will be incorporated in your product and not pay tax on those purchases, as you will pay tax when the item is sold. This might include things like frames that you buy and then deliver with a print in them. It would not include things you use in your business -- like your camera.

As for schedule C, that is income tax and the actual form is dependent upon how you file. It is very different if you operate as a sole proprieter versus an LLC or S-corp or C-corp.
