If you are trying to take the music that you have in itunes with you to the new computer then there is a utility that will allow you to backup your music and any playlists that you have in your current itunes. To do this go to File, then Library, then Back up to disc. Once you install itunes on your new computer you can insert the discs you created and it will restore all the music and settings you had on your previous computer.

Yes, there is a way to get them back. As long as you are using the same iTunes account, you can get all of your apps back for free. If you remember all of the apps you need back, just download all of them again through iTunes, and since you already downloaded them once (if they're not in your computer's system), it will download them for free.

From your old computer, go to the 'File' menu on iTunes, go to 'Library', then 'Back up library'. Copy the backup, open with iTunes on the new computer, and it should be there.
