I ran into a solution for getting Central Admin to display on Windows Server 2008 R2 today. Basically you have to open IIS 7.0 and ensure that the Physical Path is correct. For some reason the install had an incorrect physical path. I fixed it and everything worked.
Next was installing MOSS 2007 SP2 slip stream on the rest of the farm. Ensure you open the port that Central Admin is installed on or you will not be able to access. LESSONS LEARNED FROM MOOJJOO
