I don't play a mage, so I will let someone else answer that one.
The general consensus for leveling/gear is to start with the tutorial to get used to the game and at level 10-11 (when you exit the tutorial) you should stick with TSS zones (TSS = The Serpent's Spine). Those are the zones that are connected to and revolve around the city of Crescent Reach, which is now a home city for all starting characters.
You said you have a 29 mage, so you might want to start a new mage to go through the tutorial with to get refamiliarized with the game and its mechanics, and then when you're ready you can jump back on your 29 mage and find your way to Crescent Reach (very easy thru Plane of Knowledge) and pick up some level appropriate quests.
For maps, you need to download the finished versions and place them in your ...\Sony\Everquest\maps directory.
You can download them from
EQ Mapfiend which has been around a long time. Just click on "Download Maps" under the Everquest heading on the left, choose "ALL Maps" and press the "download map pack" button. It will probably be a zipped file, so make sure you have something to unzip the downloaded file with. Make sure they are all unzipped into the \maps directory, and be sure to select "replace current file" when it wants to overwrite existing map files.
Welcome back, check out a few of the other "returning player" threads for some ideas and have fun.
