Looking for advice

As you can see by the title, I have just become a new author. My book is going to print as I speak. Being new to this, and getting ready to start marketing my book, which, by the way, is titled "Tip of the Iceberg", I could use some advice from any other new authors. I've just started communicating with my Marketing Rep, but only by email. I've read all the suggestions that the publisher recommends. Just thought it would be helpful to get some first hand tips from someone who has been there.
