Up with Mobil ? Should I put through a engine flush ??!

No engine flush, If you kept up with oil changes there's no reason too, plus I've heard horror stories on other cars with those flushes.

Just buy Mobil 1, and on the jug it should say compliant with BMW LL-01, and buy a Mann oil filter. If you're doing your own oil changes, buy a bulk pack of the filters from ECS or somewhere online IMO

Just stick with oem oil no gains or point in switching to another motor oil

Just dump and fill. Know plenty of people running m1. Using Motul 300v myself.

I would stick to oem but the dealer are asking $28AUD for 1 litre bottle

Oem oil is 5w/30 Castrol. Depending on your location 5w/40 is a better oil. It has a better temp range.

Also guys how important is it to torque the filter cap and drain bolt ??! I was gonna use the old school method hand tightening / common sense ??? I mean I'll go buy a torque wrench if need be

No torque wrench needed.
