You download cydia, which is where you are able to get most of the themes or applications that will further your customization with your ipod. How you get this is very simple if you use blackra1n, and you can experience that by checking on youtube.

No, once the ipod touch has been paid for at the store it is completely free to use afterwards, unless of course you purchase songs or applications from iTunes out of personal choice.
The iPod Touch sleep/wake button is the button, when pressed once, puts your iPod to sleep. It also awakens your iPod Touch from that sleep and turns on and off your iPod Touch.
In order to reset your ipod touch you need to plug upi your ipod touch to a computer with itunes. Once you go to itunes there will be a button you can press on the ipod touch info page called "REstore your ipod touch" Click it and then you're ipod touch will be reset to factory settings.
Once you pay for the iPod Touch, you are done paying for it. You do not need to pay for the extra features.

Yes, it is true. There are many free apps for the iPhone and iPod Touch. Once you connect to the app store, select category, and choose the category you want, and at the top, there is 'Paid' and 'Free' apps. Click on 'free' to view all of the free apps available in that category.
Yes, HeyTell works from iPod Touch to iPod Touch. If using Medium or High privacy, you can connect using email (if email is set up on the iPod), or you can set privacy to Low, connect using matching contact information, then switching back to Medium or High once you are successfully connected.
No. You pay once for the application, the only time you pay is when you buy it. I should know, I've got over 400 apps stored in my computer for my iPhone and so does my sister, who has the iPod Touch. There is no monthly charge for the iPod Touch, only the iPhone, and the charges are the billings. The only time I can imagine they'd charge for the iPod Touch is if you bought something off the internet via iPod Touch, but the charges wouldn't go towards the iPod Touch, only your credit card, banking account, or whatever you used to purchase with.
