On my first run through the story I will oppose him and stand with the Dawnguard. And on my second I will fight with him. Generally I prefer the idea of joining the Dawnguard over the vampires though.
If I can help Lord Harkon as a werewolf, why sure!
If not, then say hello to armoured claws and vicious paws.
If I recall the dude at E3 said if you're a werewolf and you become a Vampire Lord it force cures the Lycanthropy but he said later on you can get it again if you like it more being a paragon of the Vampire race.

=P
Isn't there an option for a person who wants to keep their lycanthropy, doesn't want to become a vampire lord, but wishes to help Harkon anyway?
