Re: irimi nage spinning
I guess the next step is an ushiro-tenkan/tenshin/stepping back (whatever you want to call it) movement? Keeping your attitude forward and controlling uke to go towards you, you should be in a good place to throw.
I find it easier to control the direction of uke's movement by sticking and being as close to them as possible. Make sure that you apply kuzushi at all times as well.
