vBulletin is really easy to learn.
Myself it took me about one week to learn the most important things how to use it.
Also there is a manual on vbulletin.com and i think it explains most you need.
You can order the vb.com team to set up the vb for you or you can post a request in our service request forums.
Hostingdiscussions have been on vbulletin.com since a long time now, just look there, and i'm sure you'll find the answers
