I have similar issues on my network - I have a 2008 functional domain with 2 2008 DC's and 2 2008R2 DC's (one at a remote site). The policies regarding RemoteApp are completely missing!!
I'm trying to tweak the "Point and Print" policy per this article
Control Printer Driver Installation Security
However, the said policy does not exist in Computer | Policies | Admin Templates | Printers in my environment. I tried it from three different Win2008 R2 servers just to be sure, and it's missing on all of them.
I *have* been using a Win2008 (non-R2) setup with central store per Jeremy's book from a couple of years ago (when 2008 came out). Is this causing a problem? It's as if the 2008R2 policies don't exist, but I have no idea why and no idea how to fix it.

Sounds like you need the updated R2 policy templates. Try replacing your central store admx files from here: Download details: Administrative Templates (ADMX) for Windows Server 2008 R2 and Windows 7
Hope that helps.
