To Narita it can depend on where you are starting from, the Narita express from Tokyo station taking around 55mins and the Skyliner from Ueno station about 45mins.

The HND lounges are very good ( the JAL F and the Cathay F/J lounge).

Whilst HND is an early flight ( 0945 in Feb IIRC) with checkin opening about 7am if you get there at 7am you will avoid most/all of the rush hour. It is a long day flight so it is an excellent opportunity to enjoy F ( from HND, on a clear day you will see tokyo then hopefully Mt Fuji ( LHS is probably best).
I would certainly consider HND in F ( as F even in a 777 would beat CW in a 787)
