[CA] [CA11] installer bailed on complete upgrade

[NL Empty Pockets]

So need a little help here my installer bailed last minute and I'm doing a complete electronics upgrade on my own.
I'm not new to doing most everything on the boat but i Do have some questions.
Here is what I have
2) axiom 12RV ( Cocpit)
MK-10
1) axiom 7 nav+(bridge)
seatalk starter kit
2) HS5
2) ray net 5M cables
4KW magnum radar
C/P 570
R109LM 2KW transducer
Evolution AP
Flir MD625 ( I know I need an encoder and some cables for this already ordered an axis m7011 and RJ45-raynet and an RJ45-RJ45 and an additional poi)
Icom 506

So far I have the radar mounted and the cables run down to the helm and the axiom 7 mounted.

so the questions are
1) does everything talk though the sea talk or the HS5s?
2) what would I have to hook up to get the axiom 7 to have chart and sonar? that is all I really need up there.
And is the rest kind of plug and play or self explanatory?
Any advise would be greatly appreciated.
