If you retreat/lose, you'll lose all the troops that you lose unless it's Vs AW then you just end the battle prematurely. And unfortunately the best way to get R and SR is from AWs.

As for spending money, I have no idea, but probably whenever they do an event on the premium summons.

P.S: I added you in case you need more killers. :D
