Dampers are felt most in transitions- chicanes.

Since you say you need more low-speed oversteer and more high speed understeer, it sounds like you would want to stiffent the front anti-roll bar. If the total body roll is too much, stiffen both but stiffen the front more than the rear. You want to shift the roll stiffness distribution forward which should accomplish both of your handling goals.

You may need to slightly alter the damper settings after the anti-sway bar adjustment, depending on how the car feels to you. Since you are increasing your effective spring rate when rolling in a turn, that means you will be a little under-damped in those situations compared to what you were before. If the car feels bouncy and does not settle down fast enough after a chicane, then stiffen both dampers equally. The car may feel fine without adjustments, though.
