Eclipse plugins for Spring / Hibernate development?

I have a running dynamic web project in Eclipse (Java EE + Maven + Spring). I am at the point where I need to integrate a persistence layer and want to use Hibernate with a MySql database.

I am wondering what plugins would be useful for me at this point? For Hibernate should I install hibernate tools or is it not necessary? Are then any plugins that are most widely use for connecting / exploring database connections that would be appropriate for the type of project I am working on? Thanks.
