If the difference is more than $88, you could buy an additional SFO-LAX-SFO RT and dump the LAX-SFO segment. Only you can say if the inconvenience is worth the savings.
Correct. You are not penalized, but your ticket will be cancelled. The only segment that should ever be skipped is the last one on an itinerary.
