As for leveling, spamming 51-60 is usually the best; less XP per run but much faster. The 60 boss is also a pushover if you have decent aetherpool.
This, you get less XP per run but optimally speaking the returns will be far greater given how quickly you can clear that floor with a decent aetherpool. Going from 1-50 isn't optimal unless you're attempting to increase your aetherpool either as each subsequent level takes longer and longer to complete. Basically if you have an aetherpool of +40 or better, stick to 51-60 - and if you can't meet that then grind till your aetherpool is decent enough and then put your nose to the grindstone. It's boring, but effective.
