It depends on the problem you are having with your iPod Touch. Please be more specific next time as to what is wrong with your iPod Touch.
You can buy an adapter from Apple that allows you to connect iPod touch to an external screen such as an HDTV. If I remember correctly, you have to have a second-generation or later iPod touch.
Explain what you mean by "code".
No
If there is something wrong with 3G iPod then usually best buy will take it and give you the 4G.
If you jailbreak correctly, no, you keep all your songs on your ipod after jailbreaking.
All you have to do is wait the required time... Then when the time is up, the ipod will ask for your passcode once again... You must put in your code correctly the first time, or your ipod will disable itself again and this time for longer.
Only if the router you are tying to access with your iPod Touch is locked and requires a WEP key.
