Yes, unfortunately there's quite a bit more to it than that. Most publishers, as I said above, won't look at unsolicited manuscripts. So you need an agent. There are a lot of them out there. So you need to do your research and find out which ones represent the genre of your novel. Then you need to make sure they are looking for new authors. In order to submit to an agent you have to follow certain guidelines. Agents receive anywhere from 50-500+ queries a week and can't read every persons manuscript. Usually, you'll have to submit at least a one page query letter (think blurb on back jacket of books). Often you'll also be asked to include a 1-5 page synopsis of the book (in present tense) and if you're lucky the first couple pages of your novel. If they like it, you'll get a request for a partial (generally first 3 chapters or 50 pages). If they still want more then you'll receive a request for the full manuscript.
All of this takes time. I've found that journey from query to full request was about a month and feedback on the full was an additional month. I'd suggest checking out writingexcuses.com for awesome podcasts concerning writing and the industry and annemini.com has one of the most comprehensive sites on all the steps involved to getting an agent. She's a bit verbose, but definitely worth the time.
Hope that helps! Yes, it's daunting, but it (generally) ensures that only good writers get published. IMHO, self publishing via ebooks threaten to undermine that. A lot of people get frustrated when their book garners zero interest so they delude themselves into thinking that if only it were out there, waiting for someone to read, they'd be a star. But who reads self published ebooks? No one. It's a long, hard road, but Stephen King wrote for years before making it, J.K. Rowling did the same, Tolkien shopped his work around for years with no interest, and even Brandon will happily tell you about the many novels he wrote before finally breaking in. That's why rule one of writing is to write for yourself. Because for a long time it's only going to be you and your creation. Definitely a rewarding experience though, and I'm glad you're looking to move forward on your work. Good luck!
