The pedals should have come off before your took the crank off; much easier to do them with the bike sitting on the ground, chain in place. Also, can you guess which pedal is reverse threaded? (Hint: it's not the drive side this time) Once the crank is removed, you can hold the crank arm in place in a vise (padded with an old towel or something) to work off the pedals. And yes, first squirt some WD40 in the pedal threads to help loosen them.



Spacer? I've gotten an adjustable cup off by tapping off the lock ring in the same way I suggested taking off your headset spacer, above. Then improvised a pin wrench (piece of wood with two small nails) to back the actual cup out. I don't recommend this however, the proper tools work better.
