Do keep us informed, I'm interested in the Propeller also for my own 
little project, I have a development board on it's way as we speak. I 
looks like a really interesting chip. I'm looking for a board with USB, 
VGA ( 4bits/color or better) and accessible I/O pins.

 From the resistor array around the VGA connector I'm guessing that you 
are doing at least 4 bit/color, is this so?

What software did you use to layout the board?
