Purchased 6-30-14. First Porsche. Daily driver. 50k miles. Beautiful, fast and handles like a go-kart! Unfortunately, I have many questions:

#1: Water pump just failed. Metal or plastic impeller on replacement pump?
#2: Do these cars usually require clutch change around 35-40k miles as I have read?
#3: Is there any way to tell if it is the original engine? I.E. numbers matching as an American car. Will $100 Porsche Cert. of Auth. show that?
#4: Any cure for cracked water expansion tank other than replacing with a new tank that will crack?
#5: Is there any where to get basic wiring diagrams without buying entire service manuals?

Thanks. I'm sure I will numerous other questions!
