I'm stuck. Did I expect too much?

I'm pretty sure I've exhausted my "shot in the dark" capabilities (no previous WordPress experience) and what I'm stuck with is, well, not much. I honestly don't know where to go from here in regard to design. I know no coding really, but there has to be a way to do more thorough edits? Or is my lack of coding experience going to impede my expectations?

I'm using your "Product" theme - any tips to get me going again?

Sorry this isn't very specific... good sign I'm desperately lost.
