About the duplicate ring tones showing up on your Iphone, you have to go into Itunes > Itunes Summary > and then check the box that says "Sync only checked songs and videos". After that, go check the ringtones you want, then sync, and they will show up on your phone.
A good and easy ring tone maker that I use is :
