Certainly have old buddy . Was this the sort of thing you were after ??
Most online tutorials make use of iTunes’ ability to burn data disk for music backup jobs. This requires that you have a CD burner and available blank media. This short tutorial requires that you either a.) have an external HD (or iPod) or b.) a second computer to use as temporary storage. If you decide to use an external HD, make sure that it is large enough to store your whole music library. Following this tutorial will allow you to transfer your Window iTunes collection to another computer while retaining your playlists, smart playlists, song ratings, play counts, and last played dates.

However I think my first link gave instructions for saving all the itunes crappy info like playlists etc etc aswell .
Let’s start with the files. It may seem strange that there are two files with such similar names, but these files contain different information. The iTunes 4 Music Library file contains the database of all the songs in your iTunes library. It also contains your playlists, your ratings, your play counts, last played dates and more. The iTunes Music Library.xml file contains some of this same information, but is used to provide access to your music to other programs. You need both of these files to use iTunes; however, if they get deleted, iTunes creates new empty files, and only adds to them when you import music. (In other words, if these files are deleted, especially the iTunes 4 Music Library file, your iTunes library will appear empty the next time you open iTunes.)
All that remains is to back up those two iTunes Library files somewhere as well; iTunes doesn’t copy them when you back up your music files. Find a safe place where you can copy them - another CD, for example - and burn them there.
Now, even if your computer crashes and you lose everything, you’ll be able to restore your iTunes library easily. After installing iTunes, drop those two files into the iTunes folder (again, the one located in your My Documents > My Music folders if you are running Windows, or your Music folder (inside your home folder) if you use Mac OS X), and then use your CDs or DVDs to copy all of your music back into the iTunes Music folder.
Hope that helps matey as I know how much of a pain in the ***** loosing all your playlists can be .
