Brand new user, how do I get a VB homepage?

[Vital Signs]

Please respond to last post I made about the sub-domain, thx

I am very new with vBulletin and actually had to hire someone to install it for me on my site. I am trying to replicate a site such as this www.facilityb5d.com who is also using vbulletin. They however have a main front page that looks like it is a vbulletin add-on or something as well instead of going right into their forums. How do I do this and make this homepage?

Also, I just had the guy DL vbulletin, the latest one, do I still need to install that security patch they are talking about on the front page?

And one more thing, is there a database of all the mods and add-ons that a user can make to the vb forums or main site? Like if you want a chatbox, etc.?

Thanks
