Set up a plan ahead of time, aim for (4) 5* Dark Side ships and (4) 5* Light Side ships (Though I have 3 Dark Side, and 5 Light Side). Know Vader's ship is going to take you a while. Since you're p2p you can get a great head start on Boba's ship. Soon they'll offer you a packaged deal where you get his 4* ship. It's great.
I'm level 83 - finish 1st daily - My Fleet is JC, Boba, Sun Fac, Fives, Kylo (only 4*), Biggs, Ashoka, Genosian Soldier, and FOTP. (I don't use FOTP except for zeta challenge.)
Pilots matter most, so try to re-use ones that you already have geared / starred, or ones that you want to have geared / starred. I use Ackbar as fleet commander. My favorite ships out of that bunch I listed are JC, Boba, Sun Fac, Kylo, and Ashoka. Biggs would probably be better but I only have him G8. If you can get Vader's ship, that's awesome, but I think it will slow you down on your quest for zeta's. I'd wait until you have your zeta fleet ready to go.
