I have OG12, OG13, GMAT Prep Ques Pack (full version), VR and QR guides as the official GMAT Prep material. I have solved these materials more than twice. Do we have any other Official GMAT prep materials than listed above?
Older material is not as indicative of what is on the test now. For example, while OG 11 has some questions not in the 12th or 13th edition, those questions where written long before 2005 when that book was written. And the GMAT Paper tests that are available are even older.
You seem to have done lots of problems! I just want to remind you that GMAC has indicated that the problems in the Official Guides are problems that have been retired. In many cases they are not as good as the problems actually on the GMAT. It can be in your best interest to do some unofficial questions as well at this point. These materials can be more difficult and can actually give you better preparation for the test - when combined with the official sources you have named.
For example, you could use Veritas or Manhattan materials to get practice questions. In addition to the books that you can purchase there are other resources, such as the free Veritas Prep question bank that has become very popular.

And you can use some LSAT questions for reading comp and critical reasoning. Here are a couple of links to articles I wrote discussing the use of LSAT questions to study for the GMAT.
