No, don't do it!
Forgotten Realms is better omg fanboyness. (Not really, you should actually read both series; they're an important part of your Fantasy Geek education.)
My first fantasy novel ever was Isle of View when I was ten. I found it in my dad's car one day and was hooked forever. I don't remember when I stopped reading them in terms of book chronology, but the last one I remember clearly at all was, iirc, three books after the one with the family of Mundanes and the storm and such. I'm bad at book titles. >_>;;
