For the "lopsided bead" problem - make 100 spacers....then 100 more! Keep that up until you get it. Sooner or later those beads will be evenly rounded with nice, dimpled in holes. Here you are learning the glass....which at first wants to control
you. It's a great feeling when you finally are able to control
it.
Practice makes perfect, and even if the above seems incredibly boring, think of it as "work". Then, think of all of the fun and experimental things as "play". Most of us have to work and get that done before we can play, right?? So, divide your time at the torch into work and play. (I need to take my own advice, I rarely play at the torch anymore, it's been just work!!)
