I call it the timing pointer. All the ones I've seen are metal and, at least on early engines, are adjustable.

Yes.

If your not doing a valve, cam or timing chain adjustment, the cam cover doesn't have to come off. Instead, pull the distributor cap and see where the rotor is pointing when the "P" mark (TDC) is lined up with the pointer. If the rotor is lined up with the sparkplug wire in the cap for #1 cyl, your at TDC for #1. If it isn't, turn the engine one full revolution.

Must be plastic then. What year is it?
The idea is not so much that the pointer is perpendicular to engine but whether or not it is adjusted to ensure that the #1 piston is at TDC when the P mark is lined up with it. If it looks like it hasn't been messed with, I'd leave it alone. It's not that critical when doing a head gasket anyway.
The pointer can be adjusted by 'feel' (ballpark accurate), a dial indicator (more accurate) or degree wheel (most accurate).
