The site http://www.eq2interface.com/ is the site to go to find custom interfaces for eq2. I personally use DrumsUI but there is also Profit, DarqUI... In addition to those UI mod set, you should also install EQ2 maps ( http://maps.eq2interface.com/ ), a "must have" UI mod with maps with most if not all zones.
Thank you! I tried eq2maps (only 2 minutes because the servers are now down) and my gaming changed in better!
