Upgrade

I am in the process of upgrading my electronics. The current system consists of an E80 Classic, E95 touchscreen and a 48" open array radar that is no longer working. So, I have decided to eliminate the "old" part of the system and upgrade it to a E97 (replace the E80) and a HD 48" Radar to replace the old antenna. I have attached a drawing of the new system, labeled PROPOSED. So, right off the bat, my questions are as follows;
-It appears to me that I need to use a E66066 cable to connect the P319 transducer to the E97?
-If I want to use MARPA, I will need the Fast Heading sensor which is now connected to the E80 via NMEA0183 and a SeaTalk E55054 cable. According to the manual, I should seek technical help for connecting this to the E97.
-I have connected the Radar directly to the MFD via the SeaTalk HS connection. I believe this is correct.

Anyway, I would appreciate input on the system connections/errors/corrections etc.
Thanks in advance
Brian
