I am building a bike from the frame up, but have no experience at it. So please forgive me if I ask a lot of dumb questions.
With this frame AC059 Carbon cyclocross frame disc brake - Shenzhen ICAN Sports Equipment Co., Ltd. the stats for the Headset and Bottom Bracket are below

Headset: 1-1/8",1-1/2"
Would the head set below work with my frame? and is that all I need, would I need anything else for the fork/steerer tube?

Bottom Bracket: BSA/PF30
Will the following bottom bracket and crank work in this frame, this bike will also be Di2 with hydrualic disc brakes
