I would get a copy of the service manual and read it thru the section on the area you will be working on a couple of times and ask some questions about things you don't feel comfortable with before diving into it , take pics along the way to help you remember where everything goes , use baggies to separate bolt to keep them organized
If I were pulling the cam on an engine , it would include redoing the head , cam chain , sprocket maybe , jug work or replace , piston , and being the cam needs replacing ( depending on for what reason ??? ) I would look close at the oil pump
