Firstly, I'm not sure of the complete difference between the Theravada / Mahayana / Vajrayana traditions, thus I'm unable to identity with neither of the three.
Don’t worry so much about this. A belief system is not required to travel down the path. The entirety of the path can be summed up into meditating and following a moral life. Buddhism is very scientific and non-sectarian in this way. It can be practiced by any one of any religion.
Following a moral life includes 5 precepts for lay practitioners:
• "Do not kill
• "Do not steal.
• "Do not engage in improper sexual conduct
• "Do not lie
• "Do not take intoxicants (drugs, alcohol, ect)
So after I discover which path of Buddhism to follow, where can I begin to actually 'fall in line' with the faith? Do I read the stories of The Buddha? The scriptures?
Like I said above the only thing you need to do to ‘fall in line’ with Buddhism is to meditate and follow a moral life.
To learn to meditate you should take a meditation retreat. This will teach you a meditation technique properly and will strongly engrain the technique into you, like practicing a sport and building strong muscle memory. It will provide the momentum required for your daily practice.
Meditating retreats, and having your daily meditation, this is Buddhism.
Here is a good organization which holds retreats across the U.S. and world:www.dhamma.org
As far as books go, I suggest this, it is a free, simple and pragmatic: http://static.squarespace.com/static/50 ... 785055665/
