Minimal set of connected components required for functioning.

Given an iPhone 5s logic board and associated home button, assumed to be partially or fully functional, what other components are necessary to attach in order to do the following:

a) boot the device

b) unlock the device

c) charge the device

d) extract the device's stored data to a computer

e) connect to a wi-fi network from the device

I'm hoping to avoid unnecessary expense in buying parts. Would having a working:

i) battery

ii) charging port assembly with headphone jack

and

iii) display assembly

suffice for all these functions? Would connecting additional components be required (which ones)? And is the display necessary in order to backup the data, given an USB OTG adaptor and external keyboard (assuming the OS version is <= 10)?
