Your niche sounds very specific, so that will be working in your favor. For SEO I find the current best practice in long tail keywords research. Long Tail Pro, and places like MajesticSEO can help you on the SEO-front.
For converting members I believe you need to have a strong "call to action" page. This is where you ask them to register with your forum. The second step would be a proper welcome to the forum.
Hope this helps
