On the bass and treble that is not really to say, put it somewhere and go. For the WP maybe the treble a tad higher than the bass but it depends much on the guitar and the amp.
Raising the pole pieces while lowering the PU brings out a certain brightness and makes the sound tighter and more focused imho.
On the WP I would deffo say put it generally a bit lower, treble higher than bass and then raise the pole pieces between .5 and 1mm. Possibly more towards .5 on the treble and 1mm on the bass side. With the raised pole pieces I would suggest possibly around 3mm from pole piece to string when fretted highest.
That should in my mind bring out the best of the pig, though that is purely an estimation. Somewhere around that depending on gear I would guess.
Hope that helps.
