As other posters have said, missing 4th for 2nd or worse still, missing 3rd for 1st can cause big problems. The rev limiter cannot help you at all, as it is the wheels that push the revs up rather than the throttle which the computer controls, and you may bend a few valves.

In terms of pushing too hard, the rev limiter will cut in before any damage can be done. At times when I have been racing another car I occasionally flat shift 1st to second, ie. leave the accelerator flat to the floor to prevent the revs from dropping between gears. The motor just bounces off the limiter, sounds scary but no harm done to the motor (the clutch is a different story mind you, it overheats very quickly, hence why I gave up this practice).

Enjoy your boxster and drive it the way it was intended to be driven!

Hitting redline is perfectly fine (provided the motor is healthy and at operating temp). Over-revs, however, are not good. They stress the connecting rods, can actually stretch the rod bolts, and will usually show up as bearing wear in motors that have been over-revved. Furthermore, since these cars have hydraulic lifters, the valvetrain cannot keep up and it is very likely to get piston to valve contact, with its associated consequences.
