New to Windows 7 64bit

Hi all. I'm new to Windows 7 64bit thanks to a new computer. I'm somewhat of a XP 32bit veteran and was wondering what software would need to be installed to take the place of the OS ones. I already installed 7zip to cover RAR and 7zip; and InfraRecorder to take the place of Windows 7 DVD program. What others should I look at?
Thanks

Thanks for the replies. These sites are great and have exactly what I was looking for.

 

Also, for 64bit specifically, this is a nice site.
