Verticalfollow is a parameter which goes from 0 to 1. It defines how much the camera will follow a player each time he jumps. So like, for MVC it'd be higher like "0.9" or "0.8" while for something with less camera movement "0.3" would suffice. There's always a lot of debate over this, I change mine every time because for me it depends on the stage.
Floortension defines how high a character must jump in order for the camera to follow him. This will go with the character, so if you like camera movement, have a low value. If not, use a high value like "80" or "90" if you want movement, use something like "30" or "20"
Tension should be left at 50. It's the horizontal distance a character must be from the edge before camera starts moving. This may be your main issue.
