Reading your thread gave me a good bit of deja vu. I recall doing exactly what you're doing and asking similar questions. From a newb to another:
1. I like Drew's advice. Go bigger!
2. First thing I wanted to do was style a tree. In 6 months I had a bunch of tiny, dead trees with wire wrapped around branches that had no business in training. Can you keep junipers alive? Do you know what pests to look out for?
3. Teacher, Club, Books, Magazines, Articles, Videos, Blogs... In order of most useful to least (though there are some excellent videos and blogs on the web) Educate. Every. Day.
bonsai4me.com is where I was led first and where I'll encourage you to go also. It doesn't have to be a $1000 to get started, but you can't play golf with a tennis racket.
Here's wishing you much success in 2014; bonsai and otherwise.
