And by the end, this is what I had:

And I didn't really need to spend any of it, because I already had fully upgraded Power Bars and no where to use them. But I spent all of it anyway. And I ended up with my first completely upgraded ship

And I lost on the 3rd part of the boss fight, because I stupidly forgot to teleport my 4 away team back before the ship asploded in part 2. So while I still had 4 crew to spare, they were weak-ass engi, and my weapons alone weren't enough to finish the guy.

ONE OF THESE DAYS, NORMAL BOSS! ONE OF THESE DAYS!!!
