If you can complete the highest tier of credit heist available at your level you're good in that regard. Working towards beating the zeta materials challenge is good too. However, you still have room for significant improvement by moving your mods around. A few examples:
Yes, an offense set is great for Ezra but you can assemble a much better set from mods on your non-phoenix characters (including an arrow with speed primary stat and a cross with offense). Zeb has much more use for your potency primary cross than Kanab. In general you should use your mods with speed secondaries on your Phoenix.
