What could cause a car to run sluggish then make knocking noises have white smoke from the engine then die and not start again?

check your oil
is it foamy?

examine your coolant. Does it smell like oil?

is the smoke sweet smelling?

Knocking has nothing to do with a head gasket, sounds like you have multiple engine issues to me.

and finally...if changing a head gasket is simple, why does it cost so much? because if you don't work on cars all the time it is most definitely not simple and includes timing belt removal usually.
