The camshaft is what actuates the opening of the valves via tappets (Or lifters), this is why it's very important this belt is not neglected, else if it snaps piston to valve contact will occur and you can now understand why it causes the damage it does!

In between fixed to the crankshaft are your connecting rods and then the pistons are attached to these.

As to the Saph they are not really everyday cars imo/ime mainly because of the theft problems they suffer from, and yes they are expensive to run.

As said the reccomendation is 5/30 thicker oils have been known to cause problems, the visocity you have means yours will be thicker when the oil is hot.
