There is a Glassfish plugin for Eclipse available. For the Europa-distribution of Eclipse the installation should be pretty easy. Installation and the setup and usage of the plugin for a web-project are described here:
https://glassfishplugins.dev.java.net/eclipse33/index.html
I do not know about Eclipse and EJB though. But I guess that Europa has a pretty solid support for EJBs. You can find general tutorials about EJB-development on Eclipse on
http://laliluna.de. E.g.:
http://laliluna.de/ejb-3-tutorial-jboss.html
This site uses JBoss in its tutorials but given the explanations of the first link above it should be pretty straight-forward to adapt these to Glassfish.
I think it should also be pretty easy to adapt Netbeans-oriented tutorials to Eclipse.
As a last remark: It is probably good that you do not remember the old style of EJB development. EJB 3.0 is much easier and it might even be counter-productive to transfer old knowledge (some patterns for example) to the EJB 3.0 world.
