its been a while since I've looked one of these as I've mostly been doing my own old school.

Correct me as needed. I think we may be looking at the following:
Your saying the top is Caster 2.8 2.9
The next line combines to -3.5*, so is that toe .6 and 4.1* ?
Then we see 9.9 and 18.2* The only that should be up that high is steering axis inclination.
Finally we see .29 and .76 which may be rear toe ?
Here's how it must be done, sequentially, per shop manual.
Set the ride hieght. If you want to go lower than the Shop manual, that's fine. Use the Barracuda hieght as a good starting point.
If the rear is stock or a little lower, then you can go a little lower in the front ride height. All alignment setting s have to be doen at that hieght even if the car must be raised to physically make the adjustment.
Second. Adjust the Caster and Camber.
I tend go Camber, Caster, Camber again.
With radial tires and flat roads, slightly negative camber on both sides. 1/2 degree negative would be fine. Even 1/4 degree. Not positive.
Adjust the casterso they are even and in the positve range. 1.5 positive would be fine, 2.5 or 3 positive great.
If this can be accomplished moving only one adjuster cam, you got lucky.
Otherwise see what can be done on both sides. Whichever side is the least positive, match the other side to it.
Recheck the camber. This time adjust by turning both cams equally. This will keep the caster about the same while adjusting the camber.
Get at least 1/4* negative on both sides.
Finally, adjust toe. It should toe in slightly.
When done in this sequence the changes should not upset the previous item noticibly.
