Have a look at LCD Driver HD44780 16x2 4 bit 8 bit DEMO in the Propeller Object Exchange.

oops ! somebody posted even more concrete than me while i was in edit-mode
anyway:
the manual that you quoted above contains some information about the interface (the PINs and their function) and the bitbanging.
here is a website with information about interfacing an HD44780-controller
http://www.myke.com/lcd.htm
if you are common to c/c++ you can google for HD44780-sourcecode for Atmel AVR-MCUs, or ARM-MCUs etc.
using the google-parallax-search engine
gives hits about the keyword 44780

in the manual on page 134 there is an example how to make a cog wait for milliseconds
it is the file (Ch3-Ex10)-Output.spin which is installed by the propellertool
under examples\manual
