Changing all oils.F/R diff, TC, engine, tranny, PS.

[four.8is]

Taking the X and my family to California in 2 weeks and would like to change all oils before I head out.
Just checking if I've got everything right.You guys feel free to comment.

Motor oil - Motul 300V Power 5w40 -ordered 10L
Tranny oil- ZF Lifeguard 6- 12L for 2 rounds
Front and rear differentials - 3L Castrol SAF XO (OE ) (ECS or I hear Land Rover dealer sells the same stuff)
Transfer case - 1L Genuine BMW SAE 75W from the dealer

for power steering I'll just use Castrol import Multi vehicle ATF (few qts?)and exchange it in time little by little from the top .

I'm looking to buy magnetic drain (fill?) plugs too.Whats the best source for those and what size do I need for each application?hopefully no one got annoyed with this oil thread

Brake fluid was just changed with OE fluid when I did the brakes a couple months ago..

If I missed something let me know.
