@1975George Hi George, welcome to SWGOH! You're *very* early into the game, so don't expect to be able to rush to all the end-game content immediately.
A few pieces of advice I'd like to give:
1) Login every day and complete all the daily activities. You earn 100 crystals, and a bunch of credits and rewards.
2) Use those daily crystals to purchase additional energy. That energy will increase your level, and can be used to farm additional shards for the characters you need.
3) Focus on gearing up teams with synergy. As I look at your Squad Arena team, you have a Darth Vader in the leader position, but there are no other Empire or Sith allies with him, so his leadership ability is not providing much value. Instead, try Rex as your leader. His leadership ability provides bonuses to ALL allies, not just ones of a particular faction.
4) Focus your farming on a small group of characters at a time. Pick one character at a time from the Galactic War store, the Squad Arena Store, the Cantina Store, the Guild Store, and the Fleet Store, and farm their shards up to 7 stars.
5) Once you get a 7-star character, leave your guild and find one that is doing at least a Heroic Rancor raid.
6) Open up the Journey Guide, and start farming toward highly powerful characters. The Phoenix Squadron is helpful b/c it can unlock Palpatine and Thrawn for you. The preresquisites for Commander Luke Skywalker (CLS) are also helpful because he's an amazing Rebel leader.
Good luck!
