As long as you're doing one you might as well do both. And I wouldn't tie them together, but that's just me.

Rewire both.

Yes, you may run the grounds from each to the same place.

This is what you need to do: http://www.supras.com/06/techcenter/display.php?QID=69

A separate coax wire for each sensor. The shielding may be grounded at the same location; Although, I would ground the shielding by the sensors to the nearest intake manifold stud.
