Answer 1

Make sure your web.config has references to all the .net 3.5 stuff to save any confusion between versions. Then make sure your wspbuilder project is set to target 3.5

Have a look at: http://www.codeplex.com/features

Theres a feature on there to automatically enable all the 3.5 stuff for SharePoint

Probably the easiest thing to do is copy the ajaxcontroltoolkit.dll into the GAC. WSPBuilder usually adds referenced dll's to the bin folder of your sharepoint application then adds safecontrol elements in web.config but sometimes that doesn't work quite as it should.

The dependencies of the toolkit assemblies are complicated, I suggest you deploy the assemblies in SharePoint since Web.config will need to be modified and IISREST.

Please reference the following articles:
