have an answer for my iPhone sync questions

Hello...

On every sync my iPhone says it's syncing Ringtones that I created a long time ago.  I bought the songs on iTunes, then paid the .99 cents to edit/purchase the Ringtones.  These items are already everywhere they should be, in my iPhone and iTunes library.  For some reason, almost every sync indicates these same items are making the update/transfer and on the next time again, again, again....

What's up?

Another question I have is... What is the "Other" category that the gas gauge at the bottom of iTunes talking about when my iPhone is connected?  I know what "Music", "Photos", etc. are but "Other" does not give me a clue.  I'd like to know as it is using around 20% of the iPhone's capacity.

Thanks in advance!
