To upgrade to the current Gold versions, 1.1.1, just follow the instructions in the 'read me' file... unless you have some hacks or other custom changes, you should be able to just upload all of the files from the /forums folder to the same folder where you have your vBulletin installed and then import the product XML in your ACP.
Don't forget to click 'Installed'.
For more games, you'll want to keep an eye out for when v3A 2.0.0 is released. v3A has been completly re-worked for integration with MochiGames.
