So this means I'm better off setting up my remoteIO callback so it uses a buffer of floats rather than Int16's as it does now, correct?

Apple states that arm supports floating point natively. Quote:
"The ARM processor in iOS devices processes floating-point instructions natively. Your application should use floating-point instead of fixed point math whenever possible. If you are porting an application that uses fixed-point operations, rewrite the code to use floating-point types."
Also, the accelerate framework makes it possible to vectorize certain operations, and gain orders of magnitude increases in performance.
Just watch out for how you're getting data back and forth to the native audio format, because that can be a bottleneck.
