You can't do it all - I don't even understand how players manage it starting up now....
But if you have Phoenix and Scoundrels you're in a good spot.
Obviously Fett is going to be your main DS ship and you'll build around him to and aim to unlock the Zeta Challenge - probably focus on his slave 1 in the arena store whenever you see it. Better to focus on DS ships for the Challenge then maybe do a little better in Fleet Arena (but yeah, as above, Biggs is necessary for Arena). The Geonosian's and the two tie fighters can all be farmed out of the GW store, so it's slow, but probably your go to spot to star them up.
