Got it!!
Used the parallel hookup from the vendor, changed constructor pins to reflect a 328 instead of the other AVR and Bob's my uncle. Wanted to use serial for the project I was working on, but doesn't look like this will leave me enough pins. Guess its time to try to find a 4bit setup example. This is my first GLCD so I don't know if that is even possible.
Thank You floresta, usually it seems someone has my simple questions answerd before I hit "post",
the e-bay page has good pictures and a serial hookup is pretty straight forward, 3 wires and the PSB pin that I couldn't get to work, so pictuers of my hookup wouldn't have done much more. Thanks again though.
In case someone else buys this non-documented GLCD here is the code with the pinouts I used, from the u8glib Hello World example.
