We would like to implement forums into the website, but before we get too deep into developing modifications for vB, there are a few questions maybe some one out there can answer:

There are plenty of large vB-powered forums with 1000 online users at any given time. so rest assured you wouldn't be the first to try this.

Why so many queries? I find it hard to go past 4 or 5 queries on a page, if I do that I have done something wrong.

20+ queries is from the days of vB2. vBulletin 3 has 4-5 necessary queries per page (+1-2 shutdown queries), and depending on what page you're looking at, and several other conditions, this can go up to 10 and 15 in situations where Everything is enabled.
vB3 is much more efficient and server-friendly than vB2.

You'd do best to ask that over at vbulletin.com, the official vB forums. vbulletin.org is a hackers community, first and foremost.

It doesn't have entirely advanced filtering, but you can choose on a per-forum and per-usergroup basis if those posts need to be moderated first.

Thanks for your time!

vB can easily handle what you want, nearly all of your desires are perfectly met in vB3. For further technical details, contact the staff at vbulletin.com - there's a Pre-Sales Questions forum there too that you can use
