Thanks

List of things to consider
XT wheels, great quality, but quite heavy for the price, Hope hoops with Arch rims perhaps?
Hope QR seatpost clamp, very poor reputation, lots of better ones available,31.8 is the wrong size and you don't need the shim, the seat tube is more than 0.1mm thick!
1x gearing is a better bet for the bike.
Why buy pads when Shimano supply perfectly good ones?
Your predeliction with Nukeproof means you aren't necessarily getting the best from each part.

Without being rude, it looks like you may not actually know much about bikes and are buying on labels?

You're also buying a triple crankset with a double front mech

And the crankset will come with a BB so no need to buy that either!

You'll also not need this.

Brake Cables Shimano Road-MTB Brake Cable Set as you've got hydros and they come with hoses so do not require cables to state the obvious.

I also think little things, like the headset (doubt it's 1 and 1/8th), front mech - direct mount I think.
And doubt the fork will be QR, AFAIK the rear is 12mm as well, not QR.

Having had a fair amount of Nukeproof kit I would say it's great value but not great quality. The Mega frame rides brilliantly but has very poor quality paint. The bars don't have a very hard wearing finish so if you move levers etc they mark pretty badly and the stem & seat post bolts rust quickly. It's a bit of a shame because the first generation Mega & Scalp frames were beautifully made.
Also worth considering the Mega TR frame, it's lighter but still a hard hitting frame. I have done enduro races on mine, it's been over 30 foot gap jumps, off 6 foot drops, smashed through rock gardens and generally abused & it takes it well but is also light and efficient enough for all day xc rides as well. Personally I have never found myself wanting the AM model over my TR.
I wouldn't run a front mech on the Mega frame. I did and the cable routing is crap, you will get a lot of cable rub on the frame and routing it around the shock mount is very untidy & not ideal. Also, you would need a direct mount front mech, you can't use the clamp type mech. I would ditch the front mech and go for a 1x10 gear set up using a 40t cassette expander.
The rear axle is 142x12 as standard, you can get a 135x12 drop out kit but it's not cheap.
The XT wheels are very good but heavy for the price, I would go for Hope hoops instead.
A dropper post would be a good addition to any enduro bike.
The headset you got there is wrong. You need 44mm integrated top cup with 1 1/8" bearing and an external 44mm bottom cup with a 1 1/2" bearing.
The Pike forks are excellent but it's worth considering the Marzocchi 350NCR, best fork I have ever used. The 350CR is also very good and Merlin have them very cheap at the moment.
You don't need the shim for the seat post. The clamp needs to be 34.9mm, not the same size as the post.
I would also spend a few pounds extra to get an XTR bottom bracket, much smoother and mine has been going 18 months now.
If you buy the Mega frame make sure you get a spare drive side drop out, they can be hard to get hold of at short notice. And cover it in heli tape or it will look very old very quickly.

I only had a quick look, but i would perhaps consider a more agressive tyre for the front, and run the Ardent on the back only.
