I have used Visual Assist for years and I think it makes VS heaps more convenient for C++ development. The searchable file list, Go to Declaration and Rename functions in particular have been indispensable. VS2010 probably makes some of Visual Assist features obsolete but I imagine it will continue to be useful.
There are some situations where Visual Assist will stumble and not parse the code correctly, but they are few and far between, and it improves with every version.
I haven't used Refactor Pro so I can't say anything about it unfortunately.
