Yes. I jailbroke my iPod touch using green pois0n RC6 and all of my apps stayed on my iPod.
If you jailbreak correctly, no, you keep all your songs on your ipod after jailbreaking.
It depends on what software your ipod is running.
Apple has not currently put Siri on it's iPod Touch. They have released an new iPod Touch that has Siri. This new one is the fifth generation and was released in October 2012. All the old 1-4 generations will not have siri. However, you can jailbreak using jailbreaking software like GreenPois0n, RedSn0w, or JailBreakMe.com. Instructions on how this can be done can be found on YouTube.
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.
A jailbreak on an iPod Touch is when a person has 'jailbroken' their iPod Touch so they can customize the lock screen slider and make chimes when they unlock their iPod Touch. It also allows the person to put apps in folders, and download something that allows you to get all apps for free (which is illegal).

Pretty much all jailbreaking your iPod touch does is give you the installer app... Which I highly recamend you do but make sure you do the write jailbreak program or it will delete all your apps music and videos and pictures
all your current apps will stay the same after jailbreaking.
All jailbreak stores on the iPod Touch are illegal. The only legal stores to purchase apps are the App Store and iTunes Store.

Then you probably didn't follow all of the directions. Reset you iPod, follow the limera1n jailbreak directions once again, and then the limera1n app should show up on your home screen
