Right, you had a question (or questions). No, you don't need a logo to register at the USPTO. You can register your name (assuming you're aware of the rules for personal names). As for the appropriate class of goods, you would choose whatever goods (or services) you plan to sell using your name. For example, if you're Chuck Norris, that might be exercise equipment and nunchucks. If you're Brigitte Bardot, that might be swimwear and non-fur wearing apparel.
Right of publicity and trademarks. You're mixing trademark protection and the legal protection offered by the right of publicity (ROP). Under the ROP, anybody can stop the unauthorized use of their name to sell products. Trademark protection is used to make sure that a person or entity has exclusive rights to use their name on the products and to take advantage of the predictable and uniform federal trademark laws. (ROP is a patchwork of state laws.) The reason we associate celebrities with the right of publicity is because non-celebrities are not usually used to sell stuff. (There's a reason they call it the George Foreman grill, which by the way is why we have to wind up this answer as we're kind of in a hurry to unpack our new GF indoor/outdoor grill.)
PS: federal trademark registration can be accomplished for $275.
