I would get a VTF gauge mainly for peace of mind. With an $800 cart, a $20 stylus gauge is negligible. I would take the recommended VTF as a starting point, then experiment +/- 0.1 grams and see how you like the sound. With my SoundSmith Zephyr I liked it best on the heavier side of recommended range. The Aphelion 2 sounds best to me with mean recommended setting.
Re antiskate, there is also the Wally Skater tool. A bit pricy, though.
And then there is also the question of how to set your phono-stage loading. I see mainly 47 kOhm and 100 pF for the MP-500. Again, a starting point, then experiment.
