You have to manually update the OS and apps
you go on the app store then updates then click on the app you want to update then tap the update button
Restore them. Click apps on your iTunes and out the apps back on. Any if then that aren't in iTunes, just download them again.
try to restore it again and update it
Apple makes sure that all the app developers update the apps to work with the newest OS updates, so in short, no. But if you have internet access to get the apps, and a computer with itunes, you can get the updates no problem.
Technically yes because it will remove your jailbreak if you update and any cydia apps, such as installous will be deleted.
Go to software update after plugging in itouch and tapping it's name. Then do software update. Most updates don't delete anything.
No. Edit: If you mean pirated apps, no, just transfer your purchases to iTunes If you mean apps downloaded off cydia, yes they will be deleted.
Go to the app store and go to updates. You will see a list of apps that can be updated
When you Update software on an iPod touch, you get more features (Folders for apps, wireless printing etc.)

Yes, because some games are for only the ipod touch 3.0 version. So you would have more apps to choose from.
