There isn't a "how to" for these bots. When I first started using them, I was lost.
After you load Everquest via Innerspace (and you are in game) hit "`".
The type "ext isxeq2"
Once it is loaded, you are ready to load scripts.
Type "run eq2bot" for the combat script (although you can pay a few more bucks to use Ogrebot, which is WAY better--and opens up many more scripts).
Another good script is craftbot. In the console, type "craft" (no need to type "run").
Good luck
