Sorry for the late reply, but if you still need help the area you want to edit for higher attribute caps will list
Captain is a leftover from Drox Operative and can be ignored. You can find the area in the systems.gdb file and searching for either "250" or "MaxBaseStrength" in the editor you use will help you find where they are.
As for character level, to my knowledge it can't go past 100, only enemies and stuff can go past it. I may be wrong, I've just never successfully modified it higher.
