I hunt mostly along the coast and am a walk in hunter, so your needs may be different then mine, but this is what I take:
Walking stick (actually a replacement handle for a push broom) - an absloute must when walking or wading in sticky mud.
Sled/Tote - I found that is much easier to put my gear into a tote and drag it to my hunting area. The tote will float in just inches of water. I have 2; a small one (it is actually a mortar mixing tub) that is 2' x 3' that is about 9" deep, that weighs about 5 lbs. It can carry about 20 decoys and the rest of my gear. I got it at Lowes for $12.00. My large one, that I got from Cablea's, is 2' x 50", is 9" deep, but weighs 12 lbs. It can carry twice as many decoys and a lot more stuff. My sled/totes are worth their weight in gold to me.
Decoys - I only use water keel decoys, because they are lighter and easier to carry.
Dry bag - In my dry bag I carry my shells, head light, bug spray, etc.
Dove Hunting Folding Stool - Went to Academy and bought a $5.00 dove stool. I cut away the zipper compartment, leaving only the seat. Then drill 2 hole in the top part of the frame, so that I could drain the water out when I was done hunting.
Blind Material - I made a couple of 3' panel with stakes on each end so that I could stick them into the gound. I doctored up the panels by attaching some bursh or cane.
Calls - I carry 3: a mallard call, a 4 in 1 whistle call (for teal, widgons, & pintails) by Haydel, and a Haydel Blue wing teal call. We get a lot of teal along the coast.
I put everything into my tote, and hold it in place with a couple of bungee cords.
Good Luck and good hunting!
