Welcome to ePlaya, a great source of Burning Man advice, some good.
You are a little early for rideshare. Suggest regional groups, the official rideshare and Craigslist in July and August. In the mean time, great to establish your identity through your regional in person.
Also suggested, find a camp. Maybe that camp has participants from your geo that you can travel with. There are finding a camp threads.
And highly suggested, one post, one thread. And don't mind the criticism on ePlaya, it is all good natured.
