Download the LJ80 service manual, it will have all the information you want on these subjects. The gearbox filler plug is up near the steering box, it's really awkward to get at if it's still got its 4 sided plug.

Personally I've tried quite a few different oils and I like Castrol VMX-M 75w-85 for the gearbox but discussing the best oil is like arguing about religion or politics.

80/90 penrite oil for gearbox and diffs, as per the manual
