Well, you have 3 questions here: support for 64 bit, support
for Windows Server 2008, and support for CF7. Let's take them one
at a time.
As for 64-bit, there's an important difference between being
able to run on a 64-bit OS and being able to run in 32-bit or
64-bit mode on that 64-bit OS.
That said, only CF8 supports running in 64-bit mode. Further,
in 8.0 it was only on Solaris, then 8.01 added Windows (including
Server 2008 among others), Linux, and Mac.
64-bit mode is also supported only in CF8 Enterprise
specifically (not Standard).
So you can run CF 8 Standard on a supported 64-bit OS, but
only in 32-bit mode.
More on 64-bit support at the CF8.01 update FAQs:
"Does ColdFusion have 64-bit support?"

and
"Does ColdFusion Standard have 64-bit support?"

But you said you want to run CF7. Of course, that's not going
to allow you to run in 64-bit mode, as discussed above. But you can
at least install it on a 64-bit machine as long as it's a supported
OS, running CF in in 32-bit mode. More on that at
http://www.adobe.com/go/8be22ed6.
Sadly, for you, Windows Server 2008 is NOT listed as a supported OS
For CF7. More at
http://www.adobe.com/products/coldfusion/coldfusion7/systemreqs/.
To sumarize, you will need to move up to CF8 to get Win2k8 as
a supported OS, then to 8.01 to get 64-bit support, and then only
in CF8 Enterprise.
