Any Jigglypuff training methods?

[Icecap]

You see, I suck with Jiggs, and I don't know any decent training exercises to get better. Does anyone know a good training schedule? I'm not that good with making schedules..

Things I need to practice:

*Shorthopping
*Wavedash
*The throw+rest combos
*WoP

Also, can Rollout be used well in professional play? As in, using for an attack or mind games or stuff like that?
