The gland nut is what holds the flywheel on, no?
You need to lock the flywheel in so you can take a breaker bar or
pneumatic impact wrench to it. That locking is done with a special
tool:

middle of the picture -- vwplace.com sells it for around $5).
They sell a number of clever little tools -- as you dig into the car,
their usefulness will become cleaer.
As one VW newbie to another, get all the manuals you can afford -
Bentley's VW bug manual is very detailed. You may want to look into
getting the bugme videos (
www.bugmevideo.com). Those CDs are the best
tools you can have and explain it all very well in a friendly easygoing
style.
Also stay tuned to this newsgroup - there are some really knowledgeable
nice people here.
