I have the same Kayak (trophy 126), but never hunted out of it. But having spent 100's of hours in it, i would recommend something comfortable to sit on/in. I just upgraded mine with a Yak-Gear seat and it has much better back support.
I would set up the rear hatch like a cooler. A sealed bag of ice or cool pack in the bottom of a large dry bag so that you dont have blood and water pooling in the bottom of the kayak.
The front hatch I would take the cover off completely. Take another dry bag to put your ammo, snack$ drinks, etc. and use the bungee straps to secure the bag.
For camo, burlap or a camo netting. Lay the netting over the kayak and cut a section for the seat area and cut a flap for the rear hatch for easier access.
Paddle leash is always a plus but I use a paddle clip mounted on the side to keep it out of the way when I'm casting. If the paddle handle is shiny, you may want to spiral wrap some camo tape on it.
