Hi Kim,
Its a good idea to become familiar with what the historical Buddha taught first, because quite different teachings and traditions arose after the death of Gautama Buddha... and getting them all mixed up under the general heading of "Buddhism"can become very confusing.
You might like to read a PDF of the book "What the Buddha Taught" by Walpola Rahula:
http://www.ahandfulofleaves.org/docu...ght_rahula.pdf
and also there are various helpful pinned resources at the beginning of the topic list in this "Discovering Buddha's Teachings" forum on the website.
I also recommend that you read this essay "Theravada Buddhism in a Nutshell" by Ajahn Amaro, because it will take you right back to the beginnings of how "Buddhism" began.

Hope that helps.
With metta,
Aloka
