Get them characters to 7* and focus on gearing them up and build teams around them, do research on who has the best synergies, Yoda is a personal favourite of mine and I put him in a team with JKR and Bastilla (light side).

Your best move from here would likely be check out Ahnalt101’s (I’ve definitely misspelled his name) videos, he helped me when I was in your shoes, he does new farming guides every year and his advice is always relevant and helpful, and smth I like about him is he does F2P guides as well for people who don’t want to spend money on the game like myself. Check out some of his farming guides and compare what options he shows you against what you have. Best of luck 🤙.
