Welcome to the QB, you will love it.
As for your fabric find, I'm doing the HAPPY DANCE for you.
You talked about some of the patterns on the fabric are not things you would have picked, you will find that as you start making blocks with your new finds you might change your mind. I've found that some of the fabric I thought was more to my grandmothers taste, ended up making some of the best looking quilts. Remember after it's cut up and then put back together with other fabrics, it becomes something else.
Good luck and have fun, fun, fun.
