Need some guidance

Wow you are a new player, well farming phoenix is a good idea. I would recommend going for IG88 as well for credit heist. You can check this site for next events and estimated events: https://swgohevents.com/ if youre farming phoenix you'll be fine for Palp in 2 months. I would probably work towards getting CLS next as this would help with raids and moving up in arena, so that means going for old ben, storm han, leia, farmboy luke. You'll also need empire for R2, so with getting thrawn and palp through phoenix, you'll need 3 more and the easiest will be tarkin, magma and storm not the most ideal for that event but it might get you r2 at 5 stars.
If you have discord I'm happy to speak with you on there if that's easier for you Jon Snow#1981
Also Warrior released a video on a f2p farming guide for new players and what to farm first if that's of interest for you
