From what you have posted so far, it sounds like most of what you want is just a matter of turning off features you don't want. To do that, use Special:WikiFeatures. You won't be able to use Forum as in this threaded feature we are currently using. However, you can and ask them to enable wiki-style forums; which is an even older format similar to talk pages.
 * "old" galleries -> disable new galleries feature
 * talk pages -> disable article comment and message wall features
