Since the Saturn uses an overhead cam, not only do you need to remove the timing chain cover, you also need to remove the timing chain if you're planning to replace the head gasket.
Note that head gaskets typically fail when the engine has overheated and the head warps slightly. ALWAYS verify that the head is flat and properly surfaced before replacing a head gasket. It's a relatively inexpensive procedure at most automotive machine shops. Note that they will probably want to do the valves "while you have the head off", and depending on the condition of the engine, that might not be a bad idea.
Not likely. Most timing chains never wear out, and on most engines you do not have to touch the chain to remove the cylinder head.

The timing belt and head gasket are two different things. To replace the head gasket you will have to remove the head necessitating removing the timing belt. If you are going to replace your head gasket it is best to put a new timing belt, a timing belt tensioner and possibly a new water pump. BMW recommends changing the timing belt every 60K miles and the water pump every 120K miles. The belts and pumps are not that expensive and it beats having to go back in and replace them later. Note that on the M3's there is a timing chain rather than a belt.
