I think I found the problem.

I desoldered the LCD again in preperation to jumper atmega pins to the LCD pads.

I looked at the back of LCD and noticed Pad 3 had some missing gold on the back side of the pad - here's a picture.

I did some continuity checks between the pads and the little holes directly behind the LCD and there was no continuity between pad 3 and it's corresponding circuit run to it's tiny ring...

On the spiffie schematic pad 3 is labeled as CONTR - it is recieved from the atmega... That would explain why all my continuity checks from the atmega to both sides of the header pin were good, I didn't check the back side of the LCD to their final destination..

What do you guys think?
