2. Submit as many thread urls as I can to search engine?

Start filling the forum with fresh, quality content. Ideally get some friends to help. If you get good content, that's very topical, eventually people will start linking to you. But seeding a forum is time consuming.
Getting a good link or two definitely can't hurt, but if there's no content it won't help. Nobody will post on an empty forum.
