To all people much smarter than I

I have a 28' Baha Cruiser with FB.It has SEaStar helm pumps for both helm and flybridge. The hydraulic system is all 1/4" NPT fittings on hydraulic lines. I just purchased the following:

E70274-NAG ES97 9" MFD 600W SONAR NORTH AMERICAn
E22158 SEATALK CONVERTER KIT
T70243 Q24C 1350 Solid State Radar
E70245 RAY 60 VHF
E70161 SR 150 Sirius XM Weather
E66088 B60 T-HULL 12 degree Brass transducer
T70157 Evolution Auto Pilot

I have several questions most of which surround the location of the new equipment.

I understand there are many ways to design this network, but what would be the way you would design it first?

What would this look like on a diagram with connectivity (specifically power). I know sea talk provides power and data, but in doing some reading, it looked like some devices either can't or don't like being powered via seatalk????

Can you be hooked to power and seatalk at the same time? will that back feed power the network?

How would you power the seatalk network?

In regards to autopilot, what are the ideal locations for the equipment (specifically the ACU and pump)?

Near the helm pump? or next to RAM?

Bottom line: I am spending so much time analyzing pros and cons of every location, that I can't seem to decide. I'm afraid I will get 2/3 done and realize that this piece needs to be 2 ft from this other piece. I guess I just need a little bump in the right direction.

I thank you in advance for any and all help you can give me.
