Well what I see next to the fingerboard looks like a deep scratch- wouldn't worry about that. The top looks better than the back. I jave never noticed unevenness on the back of a guitar before, so I don't know about that. You should see if a piece of paper slides underneath the bridge. Just to make sure the bridge is glued down all the way. The slight rise in the center of the top looks normal to me. At least I hope it's normal, as all of my tops look similar. The strings do pull on the top. I would post these pictures in the luthiers section as you will get responses from more people with more knowledge than me.
