Sure hope you did not pay too much for the site, because you got screwed if he told you it included the content.

Seems you are going to have to do a bit more investing in licensed content first, in addition to redoing the tour before you should worry about getting traffic to the site. Got to build the product that not only people want to buy, but that you legally have the right to sell first.

There is some great advice in this forum from lots of experienced pros, but please do yourself a favor, take a step back, remove all the content you are not absolutely 100% positive you have a license for, purchase legit content, redo the tour and then start approaching the traffic question again.
