In terms of taxes, you will likely choose to have your LLC taxed as a sole proprietor -- so no advantage there.
For asset protection, a LLC will offer some liability protection, but it is not foolproof. For starters you should separate your business and personal assets, bank accounts, and credit cards. That is my understanding but I am not a lawyer.
You will want to do some research on your state's fees for registering and taxing a LLC. This can vary significantly between states.
