If full soft is too hard, and no bar is too soft, I still have the stock bar hanging in the car port :D

Not really, but tyre wear gets pretty serious as soon as you start going into positive territory.

If you really want to get silly then go up to about +2 toe and make your car to do really good wolf whistles by running a front wheel on and off tram tracks. Handling's crap but it gets a lot of attention up Brunswick St.

I recently had a wheel alignment and i am running very similar set up to you except i have random jamex springs on my koni's and (until sunday) stock sway bars.

My settings were...
Rear:
Camber: L -2.38* R -2.21*
Toe (in): L +5.8mm R +4.3mm Total 10.1mm

Front:
Camber: L -2.01* R -1.96*
Caster: L +6.18* R +5.97*
Toe (in): L +1.6mm R +1.3mm Total 2.9mm

As you can see... I had way way too much toe in at the rear.

Setting after alignment:
Rear:
Camber: L -2.64* R -2.42*
Toe (in): L +0.3mm R +0.2mm Total 0.5mm

Front:
Camber: L -1.92* R -2.01*
Caster: L +6.18* R +5.97* (caster stayed the same)
Toe (in): L +0.2mm R +0.6mm Total 0.8mm

The difference... Pretty amazing. Turning was heaps better; the car flowed easily through tight corners and had much better acceleration out of the corners. Braking was not as stable and the car now pulls to the left due to the toe on the right wheel (should really fix this at some point). I run 36 psi front and rear in my tyres (close to ff'd fedral 535 SS).

I would replace the rear bar with the stock one if you have it around, and get some adjustable end links so you can get the end links as close to vertical as possible as this will allow your front sway bar to 'work' more efficiently.
Cheers,
