re the offset thing, to get you head around the impact on the lever action on the torsion bar, imagine two scenarios (both extreme and hypothetical only for the purposes of understanding the geometry).

One where the offset is 3000mm positive and therefore the centre of the wheel is considerably inboard and another where it is 3000mm negative and the centre of the wheel is therefore considerably outboard

(if I got my negatives and positives mixed up, sorry, but you're smart and will work it out).

One scenario has a huge amount of leverage, the other doesn't. Which do you think has the softest wheel rate? Differences in reality are probably academic only.

In terms of ride height - offset itself shouldn't have an impact - the height of the axle will be the same regardless of the wheel offset (which is a side to side thing, not an up and down thing) - however using the extreme example, lots of negative camber and lots of negative offset (ie wide track) would lower the car. In the real world, it can't possibly have much impact.

Now, where's my calculator, I have some spring rates to work out!
