Don't scan negative film with 'Slide' setting if you have trouble with blocked highlights. Exposures will be shorter with this setting and highlights blocking will be even more pronounced.
Scanning as 'Colour negative' will help because Vuescan will lengthen blue and green channel exposures, but it's better to actually increase exposure in all channels and not only individual gains in B and G. Increasing gain will produce more noise in shadows, though. It depends on your processing how noticeable that will be in the finished picture.
'White point' setting doesn't effect RAW scan at all and you really should be scanning to RAW.

Or change the B/W type to a higher CI value to push the output curve to the left.
