I'm building my first quad, help me put together a shopping list with recommended parts

I am not new to flying, but my last drone was RTF and I now want to build my own from scatch. I have already ordered the frame(an Armattan Japalura 4) with PDB. I now need help with the rest of the parts. I was planing to use 3S batteries. Some tips for the building process would also be nice.

Edit: I've been looking at the Brotherhobby Tornado T1 1407 3600KV but I'm afraid it might too much combined with 4" props. Thanks for the tips btw, it's greatly appreciated
