UI That Shows Recommended Zones
 

Is there a mod that shows the level of zones?

The InfoCenter has a "Hunting Guide" page on the first tab:
http://www.eq2interface.com/download...enterv3.4.html

It display general level ranges for all the zones. It's fairly basic, and doesn't have the latest TSO zones listed yet.

For really specific information, see this wiki page:

I know you have said you are newer too. In case you did not know, you can never transfer off of the Bazaar.
