Do you need a literary agent?
Yes. And no. It can sometimes be harder to get a literary agent than it is to get a publisher, so it's a good idea to query both. When you get an agent, you can tell the agent which publishers you've already queried. If you get a literary agent before you get a book publisher, you can approach agents who are a good fit for your book to ask them if they will handle the contract negotiations for you.
You definitely need an agent if you intend to write more than one book. As to whether you should go agent-hunting, the answer is a definite yes. This isn't only because a literary agent will take a lot of the submission and negotiation workload, and because the agent has (one hopes) her fingers constantly on the pulse of publishing and knows what's going on, but it's also because an agent forms a handy cut-off switch between you and the publisher. When problems occur --- let's say that your editor's demands annoy you, or that your advance payments are late -- you have someone to gripe at other than your editor.
On the other hand, if you'd rather keep all the profits your book makes, and feel that you can handle your contract negotiations yourself, you may want to skip agents, and focus on publishers.
