I think uninstalling the CTP release alone is not enough; you also need to uninstall stuff like the .NET Framework.
Here's what the readme of VS.NET 2005 says:
To install the .NET Framework Beta 2, you must first uninstall the .NET Framework Beta 1 that was originally installed with SQL Server 2005 Beta 2. SQL Server 2005 Beta 2 requires the .NET Framework to work correctly. You must uninstall SQL Server 2005 Beta 2 before you uninstall the .NET Framework Beta 1. The recommended fix includes upgrading to SQL Server 2005 April CTP.
1. From the Control Panel, select Add or Remove Programs.
2. Select SQL Server 2005 Beta 2 components and click Remove to remove each component.
3. Select the .NET Framework Beta and click Remove.
4. From a command window, run:
msiexec /x {71F8EFBF-09AF-418D-91F1-52707CDFA274}
5. Install SQL Server 2005 April CTP.

Over the weekend, I successfully installed VS.NET 2005, Sql Server 2005 and the Express Editions of those products all happily side by side, so it *is* possible..... ;)
