89 Mustang 5.0 OverHeating?

Okay so I found out my water pump gasket was worn, and so i took that off only to find out that wasnt my only problem there was another gasket behind that one (sits just above the oil pan) that was worn, I had to take the Harmonic Balancer off to get to it, only now that I've taken everything off... Im not sure where all these bolts go because each one is different and theres about 50 of them lol. Any help guys? I need to get this fixed asap I got a job offer and this is like a once in a life-time opportunity! oh and one other thing.. How in the hell do I put the Harmonic Balancer back on!
