Do I have the right as a twitter user to host my tweets outside of twitter? Does where I posted first matter?

IANAL. You still own the content you create, including your tweets, but by tweeting that content Twitter can do basically whatever they want with that data too.

If I wanted to publish a website of your tweets, I believe I could contact you and get your permission, or I negotiate the rights through Twitter, like using their third party API.
