Stay below softcap to benefit from natural regen. There's not much point in stockpiling if you don't have a capable fleet yet - you'll just waste whatever you gathered on failed runs.

As for training, 3-2A is your best bet - good xp and no bucket usage, which is extremely important given that you barely have any (start stocking them). Some more guides on leveling:
