I would suggest using a premade game like Dawn of Defiance for your first run.
That is a very good idea. The Dawn of Defiance campaign is pretty well laid out so newcomers can have a story to follow to help them get used to rules, running a game, playing characters, etc. But it's also a role-playing game. That can be intimidating to new gamemasters. Especially when players stray from the script.
An intermediate step is to play the Star Wars Miniatures Campaign Edition (SWMCE) that you can find links to on this site. Or contact Fool. This lets you get a feel for creating characters, playing them, and "levelling up."
Or try both and see which you prefer.
