Anytime we see those two codes we generally see a failed coolant control valve. It's not impossible to do yourself, but it's a little tricky.
Those two codes can affect a number of other systems so I would probably replace the coolant control valve first and then see what codes remain.
The cam code you posted usually triggers when there is a low oil condition or a slight overheat. Again, maybe tackle the control valve first. Do you plan to replace it yourself?
