I already used premod rewrite 3.0.1.

Will premod rewrite 3.0.2 solve all the problems?

Well if you are still talking about the required code change in your extra themes, then no, you will always need to mod them for the seo mod to work properly.

Since you are using the premod, you should use this code change for additional templates : Prosilver / subsilver2 code changes

It would have been easier to tell you this before if you had posted into a more appropriated topic : "This Forum URL is not cached?" is not really related to theme issues or to the premod ...
