You probably don't need to pull the flywheel off just to inspect the internals but it will be easier to do it now than with the crank floating around once the bottom is off the engine I would think. As to if there are other bolts hiding I can't help you but someone will be along that knows these engines, try a soft faced hammer to shock the bottom free if you can't see anything else holding it.
