The LH seal is in a separate carrier that is held in place by 3 screws - make sure the O ring between the carrier & crank cases is in good condition. The more difficult one is the RH one - you will need to hook it out with something without damaging the sealing surface of the crank.
Flywheel nut is a normal RH thread, and the arrow on the pressure plate lines up with a dimple on the clutch hub not the basket. I can look up the torque settings for when you put it back together if you like?
