This is all of the info you need to know about jailbreaking (i wrote an article on it a while back)

no you will not loss all of your songs if they are all
legally downloaded and are bought from itunes.

No you will not loss any of your paid apps.

yes you will be able to sync normally.

yes you will still be able to get all of the normal apps on the app store.

Ok to start off I would restore your iPod before jailbreaking because it will have less of chance of having a problem with the jailbreak.

Go to
http://spiritjb.com/ and download it (available for all operating systems.(including Linux!))

Then open the downloaded
.EXE file and connect your iPod (
CLOSE ITUNES if it opens).

Then simply click the jailbreak button and,

Enjoy your jailbroken iPod touch.
Good luck and happy jailbreaking.
