how is the compass oriented, and how is direction transmitted?

referring to the description pictures you will see the heading symbol is opposite the connector. on the antenna side you will see a "tick" mark indicating heading. the connections depend on the application. in my case i am using it with an APM 2.8 flight control module that facilitates two connections. one for the gps input and the other for the compass input

can this hook to a raspberry pi zero 2 W? if so, how?

I have not purchased one but if it has the same GPIO as it's cohorts (Pi4, Pi3, 0), then yes. The GPS requires TX and RX. The compass needs SDA and SCL.

is the usb serial dongle included?

Not included. You can buy it here, https://www.amazon.com/dp/B07R3388DW
