YES, you can have both software installed on the same machine. Microsoft suggest to install first the previus version. In your case install first VS2008 and then VS2010.

you can migrate your project from 2k8 to 2010: just open your VS2008 project with VS2010
"Were also planning on going to Windows 7 64bit, currently have
WinXP 32 bit OS installed company wise. Any issues to look out for on this?"
I don't think so, an x64 version of Win7 includes also 32bit components.
