If you directly click sync, it will erase all music on your iPod and replace with the content of this iTunes library.
So all you need is to get all existing music/videos from your iPod to this computer and iTunes. Simply use this handy one called Tansee iPod Transfer to help you http://www.gutensoft.com/Utilities/Tansee-iPod-Transfer.htm
The whole process goes as follows:

Firstly install this program on your computer. When you plug your iPod to the computer, this program will instantly display all songs and videos on the iPod.You simply select what you wish to transfer and click "Copy" button. Done. All your selected files will be copied to your computer completely and safely. Now you can easily add those songs and videos to your iTunes library.
More importantly, this won't overwrite any original files on your iPod.And all song titles are preserved.

In this case, all songs/videos (both new and old) are on your iTunes library that you can syn with whenever you wish to without deleting any files.

Best luck!

Itunes will ask you if this ipod comes from another computer (since you formatted) and ask you if you wanna erase all thats on it and synchronise with the new llibray (probably empty !). You say NO. Then you synchronise manually by unchecking the box that says to synchronise automatically and thenn u check the box that says to mange manually the ipod. By doing that you're music that was on you're ipod will stay there, and you can coopy any new music towards you're ipod with itunes.
