For strictly managing a personal reading list, check out my project Booktracker. It's meant to be a sort-of goodreads alternative, and it includes the things on your wishlist like metadata fetching, priority, rating, etc (with lots more coming soon!).

For an all-in-one reading/watch/tracking solution, I know a lot of people really enjoy ryot, but I haven't had a chance to play around with it too much yet.
