custom slug, links and translation

Greetings,

First of all, I must say I love this plugin. However, I’d like to know how can I make the following changes:

1. Custom slug. Instead of, let’s say “book-review” to make the romanian equivalent “recenzie-carte”?

2. I would like to make the Book series, Genre, Author etc links that leads to the coresponding pages.

3. I tried to translate the files, but I still get the english interface for the published posts.

Thank you, Sorin
