Let's start from the inside and work our way out:

1)polypropelene long underwear (water wicking) inner layer to keep dry inside waders
2)Warm pants and shirt (preferably wool)
3)a GOOD wader jac/parka(preferably gore tex for waterproof qualities)
4)Neoprene waders (5mm)
5)Neoprene gloves
6)insulated hat
7)Neck gaiter
8)camera
9)binocs
10)Labrador retriever???

you should not need any calls or decoys as you stated you are going guided.

For luxury items take some snacks, water, coffee and a change of WARM DRY clothes.
