Substitute the blower for your plastic upper manifold with different torque specs and it's the same exact procedure. Literally when he torques the SC down, you torque a plastic upper to 89inch lbs instead and you don't put on a second belt.
As for a cam. Once you pull the lifters, you're most of the way there. Remove the HB, timing cover and timing set, lower the side of the subframe and out slides the cam. In slides the new one. Line up the dots on the timing set and put the cover and balancer back on. The majority of the work is tearing the top apart and pulling the lifters.
If you go for the cam and wonder about other tools:
torx bit set, I think it's a 20-25 for the cam thrust plate
HB/steering wheel puller with 3 M6 x 1.00 x 75mm bolts or 1/4" fine pitch can be used
22mm socket for HB bolt (I think it's 22, might be 23)
Cam bolt is up there..I never picked up a mm socket for it, I use a 1 1/16".
If you do lifters, you're one timing cover gasket and new timing chain away from the cam swap.
