Tinker, tinker, and tinker again with the heights until satisfied. When I take a new bass to rehearsals I also take a screwdriver and adjust inbetween songs.
On my Precisions I have the bridge saddles to match the radius of the neck, my pickup heights from the scratchplate are approximately:
E - 1.5mm
A - 6mm
D - 8mm
G - 5mm
This I’ve found is a good starting point for my playing style and I tweak from there.
