Information about Conversion – to bna'i Noach or to Judaism.
You are already a bna'i Noach. All living beings (including Jews) are bna'i Noach. You can go and start following The Seven Laws of Noah right away. This is not an organized religion per-se, however you should join an organization to complete your obligation to create courts of Justice.

The more credibility your conversion class has, the better it will be for you later on.
We can't help you, you have to go to the Jews to become Jewish. We are more than happy to point you to the Jews though; often, as Noachides, we will be living close to or be involved with a Jewish community anyway. Here are some resources I've found very useful. In no particular order..
Oh yeah, and here's some more videos.
