Hello,
it doesn't answer your hardware questions, but we have a free matlab
software to analyze EOG recordings offline, i.e. not in realtime. The
manual can be found here:
http://www.qu.tu-berlin.de/fileadmin/fg41/download/Team/Robert_Schleicher/eogui_Manual.htm
The software including a pdf manual here:
http://www.mathworks.com/matlabcentral/fileexchange/32493
Probably it is helpful regarding filtering issues etc.
Best,
Robert

> We'd like to build or buy a light-weight, portable EOG system that

> Commercial devices that we have tested all do data logging with
