I cannot comment on the LLC requirements for your state, including taxes. Legal zoom, however, is a relatively inexpensive way to set up an LLC and file the necessary paperwork in your state. If you're not comfortable with the DIY route check to see if there's a law firm (usually with a corporate paralegal) who can assist you.
Usually the Secretary of State's office will have some good information on their website about the different organizational forms. You are correct -- an LLC gives you protection of your assets, with the simplicity of taxing your earnings as a pass thru entity. Also make sure to go the extra mile to jump through certain "hoops" when operating your LLC. For instance, even if you are a single member LLC you should keep financial statements, maintain separate accounts, and timely file any reports required by your state (even if they seem stupid). This helps you legitimately hold yourself out as a profit-making entity and reduces the chance that the liability shield created by formation could be pierced later if you were challenged by a lawsuit.
The IRS has good information about taxes for LLCs on their website.
