I hope its legal, feedburner also suggest to ping which is owned by google. Check here the faq; http://www.feedburner.com/google
These are simply networks and directories and maintain catalogs of blogs. No, you do NOT have to register with each of them. The directories really don't care if you are registered, they just take the ping and then add the latest info to their directory. No, you do not have to place a link to each of these services. I don't understand your question about if this traffic is legal. Why would it not be legal? I'm not aware of any kind of web traffic that the cops will show up and throw you in the slammer for. This is kind of a goofy question. I'm not sure what you are afraid of.
