No, to jailbreak your iPod Touch, simply download the application you wish to use and follow the prompts on screen. Although it is suggested to maintain a backup, it is normally not necessary and the jailbreaking process is normally harmless to your phone. All user data is kept throughout the jailbreaking process.
Of course, downloading the wrong things to it that aren't compatible or not understanding before jailbreaking can brick your iDevice. Hopefully DFU mode and restore can get it out.
Pros: There are many features in the applications given after you jailbreak your iTouch, and it lets you change more settings that aren't available without jailbreaking your iPod. Cons: It may crash your itouch, but you should be able to restore the iTouch in iTunes to it's original settings, by clicking the button that says "Restore to factory Settings" in itunes while your itouch is connected. Hope i helped.

Restore itouch
An ipod's Hard drive/flash memory is fixed.
I would rather choose the iPod Touch considering that you can do more with an iTouch than an PSP. You can also consider jailbreaking your Itouch allowing you to get those paid apps for free. But I do not advise it, as it will void the warranty of the iTouch.
