Muzzy or thunderhead should do the trick on a properly placed shot
Totally agree magnus stingers are a great choice.
To answer your first question....yes. To answer the second, either of the two broadheads listed above would be fine as well. You may also want to look into the Magnus Buzzcuts—a popular choice amoung many low-poundage shooters and traditional archers. Either way, you'll be fine just make sure it is a cut-on-contact blade and stay away from the mechanicals.
