Disco 2 Diff Oil Change Advice (+Transfer Box)

Hi All
I'm wanting to change the diff oil on my 2004 D2 (front and rear), seems Rimmer Bros have all the filler and drain plugs I need in case of replacement/damage in removal but I cant work out if the drain plugs need a copper 'washer' like the engine sump has?
If anyone has any suggestion on type of diff oil? I understand 75/90 gear oil is the recommended.

For the Transfer box which has a leak, Im looking to check level and top up if needed until I can get it looked at, would you replace the oil entirely even though leaking or just keep checking level/topping as needed?
Also does this have a copper 'washer' on the drain plug?
