Though I don't know why Josh had to turn down coming back since the amount of screen time the character got, he would've missed like 1 episode of ONCE.
Yes, Zach Levi was their first choice for the first movie.
As for Josh? I'm pretty sure that Zach was on set for about as long as the other cast members. Not to mention, there was also all the prep work actors go through before filming starts (rehearsals, weapons training, etc...) I'm sure it would've interfered with more than 1 episode of ONCE.
