No, you should not jailbreak your iPod.
There is no advantage in jailbreaking an iPod, since it only allows for more customization of an iPod. For the iPod Touch, you could get all apps for free, but it is illegal.
It is not required, but it is recommended. You should back up your iPod before a jailbreak nevertheless...
You should not jailbreak your iPod Touch. Jailbreaking comes with many risks involved in it. Among these risks is that of voiding your warranty, so if the jailbreak actually 'breaks' your iPod Touch, the warranty will not replace it for you for free.
