>I came to the screen where I can download SSMS Express 2008 R2. The choices are 32-bit and 64-bit (I can guess by the names of files). My computer is Windows 7 64-bit. So naturally I should be downloading the 64-bit version. But - here comes the newbie question - is there such a thing as 32-bit SQL Server? That is, if my copy (or customer copy) of the SQL Server is 32-bit (and how can I find out?) will the 64-bit SSMS work? TIA.

Yes, there is. SQL Server comes in 2 versions - 32 bit and 64 bit.

Also, SSMS itself is 32 bit application. You can use it to manage both SQL Server 64 bit or 32 bit without problems.
