Dante,
The type of wader you use depends on where you are going to fish. I use a 5mm neoprene wader because I generally fish high mountain lakes where the extra thickness helps keep me warm. I fly fish off my float tube primarily for trout. I can move into areas quietly without spooking fish. I am sure it works the same for other species. You can loose gear if you are not careful. Most float tubes come with pockets and such to help this from happening. Its alot of fun I am sure you will enjoy it.
