Bromine is in it's ionic form for both reactions (solubility rules)
So you have the equation:
Fe+3 + Na(s) > Fe(s) + Na+
Half Reactions:
Fe+3 + 3e- > Fe(s)
Na > Na+ + 1e-
You'll need 3 sodiums to take in the 3 electrons given off from the Iron.
Making it:
Net-Ionic: Fe+3 + 3Na(s) > Fe(s) + 3Na+
Standard: FeBr3 + 3Na(s) > Fe(s) + 3NaBr

I want to help you, really I do. I can balance the equation, but I'm 20+ years out of high school, and I can't remember the half reaction method for the life of me. I remember learning about it, but how to do it is just gone...sorry. I'm sure there are some other eager know-it-alls who will love to help.

FeBr3 +3 Na ---> 3NaBr + Fe
Fe+3 + 3 e- ---> Fe
Na ---> Na+ + 3( e-)
