Think of it like Microsoft Word; if you learn how to use that program it doesn't mean you know how to write a novel.
Penny Stealer, just sit down and read what each tool does, then play with the program to see what you can do. There is a lot to think about when writting a show, it is more than putting dots on the page. Also, being "only a 1A group" does not make it any easier to design than a 6A group. In fact many times I find it more difficult to write for a small group and make it effective than a large group.
Don't let this scare you from trying it, go for it, have fun, and see what you come up with. I actually worked for a great designer as his field tech for about 6 years before I started designing shows. I got Pyware and played with it to learn it, reading the manual probably would have been easier. Now I watch a lot of shows just to study what other designers do and how I can apply their techniques to what I do. I do not copy their moves, but I watch how they develop forms and transition from one to the next to create visual effects. I am always learning more everytime I write a show.
Have fun and good luck.
