Answer 1

Do not write specific dao for each entity. You can implement one generic DAO that does 90% of work for all entities you need. You can extend it in cases you want specific treatment of certain entities.

In project I am currently working on we have such DAO that wraps Hibernate session providing methods similar to those that you described. Moreover we are using ISearch API - the open source project hosted at google code and providing very convenient criteria building interface for Hibernate and JPA.
