Leopard 4074 2000kv motor will rip in that boat, either a Swordfish200 or Turnigy180 esc. This is a good setup that lots of people have been using, me as well in my mono. Lots of info available on this motor esc combo.
A metal gear high torque servo for rudder, they take a pounding so metal gear is a requirement for longevity.
Your battery choices are fine for any of them.
I'd go for the 3 channel radio, it has a 10 model memory, this means it will store all the settings for up to 10 different model/receiver setups.
A charger with some watts behind it is the last thing you haven't listed, don't get a cheap 50 watt charger, it will take hours to charge you batteries, buy as powerful a charger as you can afford. It can take an hour for a 50 watt charger to charge one 2s 5000 mah pack!
I think that hull is a bit big for a 36mm motor, The overseas retailers are overly optimistic about power requirements. Big part of the reason why most chinese RTR boats need to be pretty much gutted and upgraded right off the bat. SMall motors and esc's.
