the bolt missing is supposed to be , its where you would fit the wading plug if you go in deep water they are normally not there
the pipes leaking are steering pipes and the red fluid is indeed the steering fluid, might be the pipes are past their best or the metal part on the chassis has chaffed where it,s clipped on, thats quite common
if there,s a lot of oil and a drip onto the floor from the swivel it may just be the swivel seal thats leaking, check the chrome is intact on the swivel and not pitted and rusty, this can cause the seal to leak
hope that helps a bit :D
