Hi Ccaprice, you have a lot of catching up to do.
The bazaar is now an automated function. You click on one of the "open book" pedestals to get to the Plane of Knowledge, which is a hub for many newbie zones. One of the great entry ways on one of the walls of the zone will take you to the bazaar, the other the guild lobby. Simply approach the large door to zone. Use your map feature to find out where the zone-in to the bazaar is. Buy a "trader's satchel" from merchant tekrama, go stand on the wood platforms deeper inside the zone, and type /bazaar and /trader. /trader is where you set prices for your goods. Bazaar is a browsing / search function - and it's very handy. You also have the option to turn off all other traders (make them invis) so that your computer won't lag - also very handy, as there are often more than 500 other people in the bazaar.
for the most part, EQ is a different game from when you last played. I recommend strongly that you have all expansions, at least up through Serpent's Spine (all except Burning Sea). East and West commons have merged, as have South Ro and Oasis, and even West and North Freeport. There are close to 450 zones in the game now (I've completely lost count). You probably won't find much luck with the old newbie zones. The exp and the loot are poor, and since there are so many zones, the players have much more room to "spread out" in. I advise following the advice of the poster above me and sticking with the hot zones.
There are new races, new classes, tons of new quests, new spells, new items galore - too much for most folks to keep track of, and that's the beauty of it. I recently started up a toon on Zek - it's better now since no one can loot your corpse if they pk you. There are a large number of sub-lvl 50's on zek. I also hear that there are a lot of people on Stromm.
P.S. Playing with a mac is a bad idea - you're basically limited to Planes of Power (which came out in summer of '03, i.e., ancient history).
Hope this helps.
