I cannot help with a lot of these, but if you are going to Takarazuka, down the street from the Takarazuka Revue is the Osamu Tezuka Museum, which should be a must see for any otaku. It is inexpensive, small, but a lot of fun, and the young ones will enjoy it, too.

There are lots of restaurants and shops on Flower Road and near the station, so finding a place to eat will be no problem.
