Sorry, I was off island when you first posted and just saw your question today.
There is no good route all the way in from Makakilo. Much of Farrington Hwy passing through the old cane field area has fast drivers, that too often do not pay attention. That is the worst section of the ride.
The Bike path is not currently constructed between the west side of Waipahu to Waipahu Depot Road. So you still need to take Farrington Hwy, turn right onto Waipahu Depot Road and left towards the fire department repair station (if you reach the police academy, you have traveled too far). The Pearl Harbor Bike Path starts across the fire department repair station.
The Waipahu section was suppose to be constructed many years ago by the State, do not hold your breath.
The Pearl Harbor Bike Path is a decent ride. Some degradation of the path surface exist due to tree roots and heavy equipment being run on the path. None of the path is lighted, you need a good head light. No need for tail light when on the path, but I suggest you run a tail light on the roads, night or day.
The path does cut through the CINCPACFLT boat landing turning into a roadway, but it is gated. If you have an active duty military ID, there is a card reader to open a small gate for cyclist (0500 to 1700 I think). The card reader has been broken, so there is one of the large gates open to let cyclist through for now.
At the Arizona Memorial, you will need to ride up to Kam Hwy to continue.
From Makakilo, the Pearl Harbor Bike Path will only cover about half your commute.
