Yeah, there's a field in the Admin Control Panel once you install Downloads II that lets you add the all the file extensions you want to allow your users to upload. It also adds permission based settings to your User Groups in case you want to limit the download/upload access to only certain User Groups.

I'm not sure if you have access to the Tag option under Modification Settings within the mod threads. It might be something you don't get until you purchase a license, but you can check. You should, at the very least, be able to add any thread here to your subscriptions list.

One of the nice things about vB is once you do buy a owned license, you have access to all the current upgrades for one year. But even once the year is over, aside from being able to run your forum indefinitely, you'll still have access to all versions of vB that existed up to the point your license expired. So you don't have to renew if money is tight when the license expires. You'll still have access to member support, both .com and .org forums, and any upgrades that where made available during the time your license was active. And that way you can wait until your in a better position to pay the renewal cost, and gain access to the most current versions that came out during the expiry period. So you might want to take that into consideration when holding off buying.
