the timing belt on a dohc is just aligning a set of head pulleys and not just one, if you have done timing belts before this one isnt terribly different.
You should install the water pump at the same time, as well as the thermostat and housing (if it is still plastic).
look to daox's uild thread for pictures of the pcv system, its not necessarily a valve.
in what context was "total atf" ? to me that mean is you were able to drain the system dry, that would be the amount to put in, verses, if you drain whats available in the pan, then you would only put in that amount.
