Mazda Repair: R&R 1993 Mazda 626 Timing Belt, crankshaft pulley, crank sensor

Question
I'm trying to help my son replace the timing belt on his 1993 626.  Is there an easy way to do this.  What is the correct procedure.  The head is off because we need to replace one of the cams.

Any tricks that you know about that will make replacing the timing belt easier.

Which wasy do we turn the Nut.  Left or right?

Thanks for your help.
