You will get 2 reports. One for the bees, looking for mites and nosema. The other for the comb looking for AFB, EFB. That is your starting point. If all comes back ok reuse the frames of comb. They will build quickly if they are not drawing comb.
Do an inspection once a week until you start to figure things out. Check the hive bottoms for charged queen cups starting around the 15th of May or sooner if the weather starts warming. Check for back filling of the brood nest, and excesses amount of brood where the queen has no place to lay. Put your supers on early in anticipation of the flow. May 1 is not too early. Don't use a queen excluder between the supers and the hive bodies. That way she will always have room to move up if she needs to. Don't worry about the lake. Michigan is all swamp land and lakes with 100% humidity daily, and we have successful colonies year after year.
Looking at the one picture of the feed tray on the top of your box I think I see wax paper under the sugar. I would not do that. You are creating a vapor barrier above the bees or a moisture problem. You want the the sugar to absorb the moisture not transfer it back on the bees. Preferably don't even put sugar or winter patties on until you know they may need them. There are warmer days in January , February and March to check on food supply. If lite feed.
