It might be that i'm not quite sure what you mean but here goes.
Yes, they are both x64. Bottomline is that 2008 R2 is a revised version of Server 2008 with some new features.
And yes, you can upgrade Enterprise 2008 to Enterprise 2008 R2. Not all updates are available though. Mostly if you have different version of server 2008 and 2008 R2.

Do keep in mind that the upgrade has to be the same CPU configuration. So a 32 bits version cannot be updated to a 64 bits version.

Here is a link to supported upgrade scenario's.
