Got her, Now what?

Got her(guaranteed) on 5th pull(50wishes), now what to do with the rest of my wishes(about 200 left, hard earned, F2P)? Get new support char for my Noelle or wait and get her best weapon, Redhorn?

I don't have Redhorn, Xilonen, Navia or any 5star that works with Noelle except Furina that I just got. What is the next best thing to pull for my Noelle?
