Help with N54 major maintenance DIY order sequence

I am starting a big list of maintenance on my “new to me” e93 which has about 65k on it . I have gathered parts to do all of the following and I’m looking for input on recommended sequence for efficiency. Please let me know if the below order is far out of whack. The only thing I’m waiting on at this point is new motor mounts which I figure I’ll do while doing the oil pan gasket.

Valve cover gasket (almost completed) and plugs/coils
Walnut blasting and new intake gaskets
Oil filter housing gasket and cooler gasket
Water pump and thermostat
Belts/pulleys
Oil pan gasket and motor mounts

Anything else major I’m forgetting or anything wrong with the above sequence based on experience? Any feedback is appreciated. Some little things like the RB pcv valve I'll do while in there.

Intake Clean & Oil Filter Housing Gasket

I know you have had fun with the valve cover gasket replacement. I used Hondabond sealant which was recommended to be by my BMW dealer.
.
Once you have removed the intake you will have access to the oil filter housing gaskets (2) if you have the oil cooler & hopefully you do.
.
.
When I owned an N54 the only other thing I did that is not on your list are the injectors. Easy to replace but a pain to program.
.
I now have an N55 but have only performed 1 oil change.
.
.
Have fun -- it will all be worth it -- my old 07 335i is running strong with 145k miles with her new owner.

Just curious, are any of those items leaking/failing at 65,000 miles?
