bonus Question: I will also have a NMEA 0183 intelliducer connected to a GMI-10 on the N2K backbone. I assume depth data is shared across N2K to both MFDs? (this is in addition to the GSD22 networked to the displays, and separately switched).
10 ports total, 5 each. Each 4210 will have : port 1 and 2 are TX and RCV. 3 and 4 are RCV only, then you have 1 port dedicated for a GPS antenna.
Per the link below, Depth info will xfer from 0183 through the NMEA 2000 network.
As far as what information gets shared where? Don't think there is a list of data shared on their marine network but for nmea information they had this article(page loads wierd, may need to scroll down) :
