[MyIS] Jordan : I think how many users you will have browsing your forum and gallery will be quite an important factor in what sort of host you'll need
if it's just the 1 or 2 people per day... probably almost any host will be able to handle the usage.
but that changes a lot when the number of users increase.
whether you can get by with a high quality shared hosting plan or will need VPS or dedicated will depend on the number of users.
My buddy runs
http://rockysrubberroom.com/forum/ (vBulletin v3.5.7) with
HostGator's Swamp plan.
Currently has around 35 users online and 10 guests... "Most users ever online was 347 on Dec 01, 2006." not sure how that would compare to your predicted usage, and I'm not familiar with how vB v3.6.4 compares to v3.5.7....
My site is also currently hosted by
HostGator, received over 10,000 pageviews on Saturday:
http://josiemaran-world.com/gallery/ and moves around 6GB of data per day
I moved to hostgator on Friday due to the increasing popularity of my site recently thanks to a much improved google ranking, and some small problems with the previous host.

There are probably many other hosting plans which can provide what you need, but I'd personally recommend HostGator as a quality shared hosting plan, judging from various friends' experience with them as well as my recent experience after moving to their server.
