Correct.

It gets added (multiplied by skill WDM modifier ofc) separately. It does not take part in the conversion.

Your elemental damage will be carried by all weapon damage skills.
Example: your barb has 100 physical damage on normal attack and a helm that adds 20 fire damage. Total damage per attack = 120. Stormblast has a 1/2 WDM modifier and converts 100% physical to lightning. So what happens when you stormblast? It converts the physical to lightning and multiplies it by the modifier and adds the ele dmg also multiplied by the modifier. So you will end up with 50 light + 10 fire dmg per hit (and 0 phys).
