Furuno 1964c

I was thinking about purchasing a Furuno 1964c for my fishfinder and for radar. And a Garmin 5012 for my plotting, and gauges( speed, temp, rpms etc) and weather. I what to use the airmar B164 transducer Ik for the Furuno set up.
My questions are: 1- This this set up too much for a 265 grady white express 26 foot boat.
I fish off of Long Island , so I need a good fishfinder.
2 - Does the Furuno 1964c come with the open array and everything I need
to set it up? I think the only thing I will need to purchase is the 4 or 6
foot antenna.

I will be taking 6- 8 canyon runs a year. And mostly fish in waters less than 250 feet. I also need a radar that can track birds. Any help and advise you can give me on a good setup would be great.
