Hey Tim I don’t know Vegas but I can solidly back up your feeling that FCP and Avid are the industry standards and if you want to work professionally as an editor you need to learn both. I started on Avid but about 2 years ago got my own FCP at home just to learn it because of all the calls I was getting.
Other than books and training classes I find one of the best ways to learn anything is jump into it and do a project. FCP is easier for this in that you can easily afford a home system and sweat out the learning curve in the privacy of your own home. Find something easy-ish to work on like a personal or student film. I did wedding videos for a guy, not a lot of money but I learned the basics pretty well.
