There are some instructions about setting up geotools; however can I ask you to move to the user list (the developer list is for people working on the library :-) )
The various tutorials point out that you only can use one of the gt-epsg jars (hsql, h2, postgres, etc...) at a time; the gt-epsg-hsql is recommended; gt-epsg-postgres is used when you have set up a local posgres database (perhaps for use by a team?) and they would all like to share a database of epsg codes.
