Even into late December, Florida can be either quite humid or quite chilly. Mother Nature can be fickle. Mosquitoes and insect annoyance factors (ticks, chiggers, flies, etc.) are always a consideration and NOT having gloves and a face/head net is your choice, but not recommended. Easy enough to stick them in one's pocket if conditions warrant. Snake leggings - never worn and I don't use but all locations are not the same and some places are crawling with poisonous snakes. Therma-cell is a great product. So is Permethrin. Search that topic on the GBO boards for a wealth of information.
FL law in regard to hogs(2010): They are considered "domesticated wildlife" belonging to the land owner upon which they occur. On Private land there is no size restriction, no bag limit, and no regulated hunting season. Hunting with a light I do not know, but DEFINITELY NOT one affixed to your rifle or shotgun.
