Sync It With ITunes - Lost All My Touch Music In My Library ?

I have just bought an iPad2 which was delivered two days ago. I've only had it two days and it has already caused me unforeseen problems trying to synch it with iTunes. Today, I've had to re-install iTunes on my computer, lost all my iPod Touch music in my library and have been bamboozled by all the horror stories I've read on the Web relating to synching and losing data. So after a frazzled day, I am not a happy bunny and am beginning to question whether I have done the right thing investing in an iPad2 when it has messed up synching my iPod Touch already. Today, it also took a two hour phone call to Apple Support to fix and delete two rogue Bonjour files from my computer so I was able to re-install iTunes.
