You may just need to work on your cartridge alignment, VTA, azimuth, and tracking force. Start with VTA as neutral as possible and then adjust up or down. Tracking force should start at the high end of the manufacturer's recommended range.
I've heard good things about the Mint protractor, and I can recommend the tracking force scale that Mapleshade sells. (They just add the shelf to an inexpensive scale, so you could just buy the same scale and make your own shelf.)
On the other hand, while I have no experience with that arm, I haven't found Benz carts to be particularly stellar trackers. The Audio Technica carts I've used seem to do better with highly modulated records.
