Also it says in iTunes that how much "media" can I sync into it and it says 7,4gb but it should be 8,0gb.
That .6 GB is the amount of space that the operating system takes up. You're rarely going to get usage of the entirety of the storage space it says is available on the box. The freezing when you sync with your PC seems more likely an issue with your PC than with the iPod.
If you just got your Nano 6 months ago and are having problems I would suggest taking it in or sending it off for repair, because it's still under warranty. Whenever I've had issues with my iPods the Apple Store has just replaced them.
That said, I think buying an iPod touch would be frivolous, especially for someone who's 13, has no money and has a Nano that's under warranty.

LOL, you joined this site just to say that? Really?
Why don't you go make some vinegar with those sour grapes.
Nice username, btw.
