Help with some advanced techniques

[wts3]

I'm having the absolute hardest time learning dash dancing and up-b oos. Does anyone have any helpful advice or is it just practice until it becomes muscle memory? For the record, my dash dance looks like I'm just pivoting in place and every one in a while I can get it right, does this mean I'm going too slow? My problem with the up-b out of shield is I'm doing a short hop first, would that be because I'm not pressing b fast enough?

dash dance- tap left (let go) tap right (let go). repeat. You'll find this much easier than keeping your thumb on the control stick.
UpB oos works best with tap-jump. Just hold shield then tap up- and immediately press B. viola.
