Here let me help... (TL;DR at bottom)
Ships: Work on Grand Moff Tarkin's Capital Ship until you can get Thrawn and his respective Capital Ship. Don't worry about Zeta mats until you are lvl 85.
Mods: Work on Health tiers until you three star the 3rd tier, farm them to put onto your squad arena characters and characters used for events, challenges, and mod challenges especially. That's what I am doing. Research mods and how to use them on certain characters, I am still working that out, but Speed is the most important stat.
Gear/Levels/Stars: Don't worry about stars to much, just star up your characters that you use in events and challenges to 3 star them. Levels don't matter besides for Gear and Abilities. I see you have a few mismatched characters up there. Work on First Order's gear and work on Resistance for the Speed Mod challenge.
Factions: You will be using First Order for now as you have most of the essential ones. Get Kylo Ren (Unmasked) as fast as possible and gear him up as he will need to be your First Order leader. His ship is also very powerful and is farmed there. Star and gear up the First Order Officer, First Order Tie Pilot, and First Order Stormtrooper to put them in your team later. First Order Stormtrooper will replace Phasma as she isn't too good unless she is leader.
Guild: I think that you should stay in the guild you are currently in to get good gear, needed very badly by a lot of characters in the higher levels of gear. The guild tokens are useful for buying gear and character shards that you need. Only buy gear that is crucial to your characters you are working on, once they are good, you can work up others. With the inflow of Raid Han and/or General Kenobi shards from the Heroic raids, you will be able to get a really good team as soon as you can get those characters 7 star and high gear, they are very powerful.
Squad Arena: Use Phasma leader still, Rey (Scavenger), Princess Leia, Stormtrooper Han, and Kylo Ren until you can get your First Order up.
Characters: You need Princess Leia, Stormtrooper Han, Obi-Wan Kenobi (Old Ben), Farmboy Luke, and R2-D2 for Commander Luke Skywalker, so star up an Empire team to get R2. Don't worry too much about it right now, just focus on First Order. Commander Luke is a very good character, one of the best.
After you work up your First Order team, you need to start farming the Phoenix Squadron characters: Hera Syndulla, Ezra Bridger, Chopper, Kanan Jarrus, Garazeb (Zeb) Orrelios, and Sabine Wren (optional, she is super hard to farm). The Phoenix characters will be used for the Thrawn event, which is very difficult. Thrawn is one of the best characters in the game.
Jedi aren't too good right now, so only star them up if you really want a 7 star Grand Master Yoda.
Empire teams are useful, so star up your current Empire characters and use a Rebel team to get Emperor Palpatine (If your current Rebels can't get him, you should be able to gear and mod them until you can, he is a pretty easy event).
That is all I have for you! Sorry it is so long, I was trying to cover everything!
TL;DR
- Work on Health mods until you can get a Resistance team for Speed mods
- Gear and star First Order Characters you have now, get Kylo Ren (Unmasked) and replace Phasma with First Order Stormtrooper once he is high enough.
- Stay in your guild
- After First Order, get Phoenix
- Don't work too much on Jedi
- Get legendary and Hero's Journey characters (not Rey (Jedi Training) yet, she is very hard to get)
