Mac Pro (Intel) and Epson Drivers

I have recently converted to a Mac from the PC universe. I am very familiar with
the Epson driver configuration on the PC and have successfully created my own profiles
using PM5 as well as using the fine profiles from Bill Atkinson. But I am struggling a bit
with the Epson driver setup on the Mac.

I am using an Intel Mac Pro running 10.4.8

Things I am struggling with - uni/bidirectional printing, resolution, color
management, etc configurations in the driver... Is there somewhere that you can point to begin
the learning process over again? Cannot seem to find much in the way of documentation at
Epson.
