For 720s you can't really do them standing still, you either need to buffer it during a jump, dash, or during another special move. For 360 motions I just do the full 360 since it's easier for my brain to keep track of it that way. I find them easier to do on pad since you can really feel where your finger is sliding while you're doing it.
This is a pretty good video on shortcuts for 360 motions.
