Question: How do I replace the timing belt?

I have a timing belt that is missing teeth and needs to be replaced. I have removed the wheels from the water pump and crank shaft that turn the serpentine belt. There is a metal pipe running from the water pump assemble that prevents me from completely removing the cover plate over the timing belt. Should I disconnect this hose? Also, I want to make sure I have the white hash mark on the cam-shaft gear and the crank-shaft gear in the proper position before I replace the timing belt cover and avoid risking blowing a piston (so a friend tells me) I was told that the white hash mark needs to be in the top most verticle position on both the cam-shaft and crank-shaft gears... is this correct?
