Right now the guys doing second FTP accounts are doing Lando, St Han, Biggs, Boba, and then whatever from guild shipments. Once you are done St Han get IG-88 and once you start fleet work on Wedge from fleet shipments and then Cantina once you hit level 69. Wedge lead rebels isn't the best possible team anymore, but all the better options require very hard to get empire toons or zeta abilities that won't be available to you for months.

Good advice except sthan and ig88 are both arena shipments, I'd farm one at a time and maybe grab cad bane or Biggs from gw once you get there.
Arena:
Ig-88 then SThan
Cantina:
Geonosian soldier and Boba
gw(once unlocked)
Biggs
