To detect if the target machine is 32-bit or 64-bit you can use VersionNT64 property. This property can be used as a launch condition to stop the 32-bit package from installing on a 64-bit machine. A 64-bit package cannot run on a 32-bit machine and is stopped automatically.

For detecting SQL Server there are multiple approaches. For example you can search for registry values or use a custom action. Perhaps this article will help: http://blogs.msdn.com/b/sqlexpress/archive/2006/07/29/682254.aspx
