Dragon's Breath is book number two in the series.
Once Upon A Curse
Yes
E.D. Baker published The Frog Princess. The author published this children's novel in the year 2002. There is a movie called The Princess and the Frog that is based off this book.
There are several book adaptations of the 2009 animated film. However, the plot of the film is based on the book The Frog Princess by E.D. Baker.
There are 8 books in the whole series. I have read all of them! They are: The Frog Princess, Dragon's Breath, Once Upon A Curse, No Place for Magic, Salamander Spell, Dragon Princess, and Dragon Kiss. E.D. Baker is finishing up the 8th book of this series, A Prince Among Frogs, and should be released in September 2010. (These books are in the order they were made. I suggest reading Salamander Spell before reading them in the order they were created in. I say this because it is like a prequel and the book 'The Frog Princess' will be easier to understand. Hope you enjoy this series of books!)

The frog princess.
Yes. There are already 6: Frog Princess, Dragon's Breath, Once Upon A Curse, No Place For Magic, Salamander Spell (the pre-quil), and Dragon Princess. E.D. Baker is going to make another one, but said that her titles change a lot, so she isn't allowed to announce it. According to her, it will be the last one in her series. She has also written another book called Wings but is does not fit in the Frog Princess series in any way. The Disney movie is also going to have twists of her books in there so be on the look out!
It is similar in ways but slightly different in others. But it has the same basis: A frog talks a reluctant girl into kissing him and she turns into a frog. They end up in a swamp and seek magical help to turn them back. They learn how to eat like frogs, have trouble with their tongues, and befriend other creatures. There many other similarities. This is because Disney based Princess and The Frog on E. D. Baker's book The Frog Princess.
