On the IntelliSense problem ... we've fixed some IntelliSense bugs in build 1172 which you might want to try out.
The Visual Studio 2008 version is http://www.sapphiresteel.com/downloads/amethyst_beta/amethyst_VS2008_1_5_0_1171.zip
The Visual Studio 2010 version is http://www.sapphiresteel.com/downloads/amethyst_beta/amethyst_VS2010_1_5_0_1171.zip
Not sure if that will fix the problem you have - but it might be worth a try.
And, yes, AnkhSVN is good - much better than I expected
Also, build 1171 has the SVN import functions.
