The water pump pic..

The mounting pad beneath it is for the oil metering pump for oil 
injection into the rotor housing. If you are premixing oil in your fuel, 
you can cover this with a blind flange/ cover plate. If you are going to 
use oil injection, you need to mount the oil metering pump at that 
location, and determine how to actuate it - its servo driven.

Second pic.. with the filter pad.I am 90% sure you have your in and out 
backwards.. the oil supply TO the filter is the one you have labeled 
'out'. The oil passage FROM the filter TO the engine/eshaft is the one 
you have labeled 'in'. You can confirm this by blowing air from an air 
gun down the passage you labeled 'out' and have it exit at the bottom of 
the iron in the port where oil enters from the oil cooler.

 Just below where you call it oil temp sender, I suspect is the oil 
pressure sender. Thats where it is on the second gen engines.

The 5/8 pipe coming out below that is hot water out to the cars heater. 
Plug this unless you are going to use hot water in a heater core for 
cabin heat. Below that.. the tapped hole in the aluminum rotor housing 
is for oil return from a PSRU. Its tapped already and you just have to 
put your fitting on there and hook it up - it drains into the oil pan.

All my experience is with the 2nd gen 13B..
