Yes, it is very common to create a logo for identification of your brand. In US practice the mere "use in commerce" of the logo in association with your goods or services may give you some state and federal protection.
However, a registration (state or federal) will give you better protection, not to mention notice to the public of your claim to proprietary rights in the logo.
So, to answer your question, yes you can "put trademark" on a logo, which means you can enforce the logo as a trademark, or you can put "tm" on the logo, or you can register it and put the circle-R on the logo.

No. Since 1989, when copyright law was amended to bring it into alignment with the Berne Copyright Convention, it is no longer necessary for a copyright symbol to be displayed to establish or maintain protection. Copyright exists from the moment you create an original work, and that can be something as simple as a photo of your child.
No, everything on the web is not copyrighted. You have to claim copyright by placing a copyright symbol or getting a license claiming it's protected.
Signatories to the Berne Convention (which includes the United States) cannot require formalities. Before Berne, works were only protected if they were published with a copyright symbol and registered with the Copyright Office; since Berne, works are automatically protected as soon as they are "fixed."
