New computer and setting up itunes and sych iphone new to new computer

Question

hi guys,
Just formatted my hard drive i did backup the iTunes folder inthe c:\users\name\my music\c folder e.g. apps music etc and i did also backup the apple computer folder in the c:\users\name\ app data\roaming\applecomputer folder(which has the iPhone and iPad backups in it),
I have just formatted my hard drive how do i restore iTunes? do you just authorise the computer and then click and drag the music folder into iTunes so all the apps and music go into iTunes and then do you copy and paste the apple computer folder (from the app data folder) to the new computers app data folder? then just plug in the iPhone and sych?

i did some reading and couldn't find much on how to restore iTunes from a backup there is heaps showing how to back it up! I did find this in the apple discussion forum. ( i think its for people who havennt made a copy of the applecomputer folder.
I just want to recover my itunes so i can just plug in my iphone and i dont loose data from when i did the backup 2 weeks ago, i can just plug in and contine like being on my old computerI
(By design, the iphone will sync itunes content with one computer at a time. Any attempt to sync such content with a second computer will result in ALL itunes content being first erased from her phone & then replaced with the content from the second computer. This is a design feature and cannot be overridden. Because you are replacing your GF's computer, her phone will see this computer as a "new" computer. The itunes content sync is one way: computer to phone. If you have photos that were synced to her phone or music ripped on her own that were not backed up, you will first have to extract them from her phone using third party software, before you do anything else, as Apple makes no provision to do so:

Once you've done that, do the following in the order specified:
1. Disable auto sync when an iPod/iPhone is connected under Preferences>Devices in itunes(under the edit menu if using Windows).
2. Make sure you have one contact & one event in the supported applications(Address Book, iCal) on your computer. These entries can be fake, doesn't matter, the important point is that these programs not be empty.
3. Connect her phone, iTunes running, do not sync at this point.
4. Store>Authorize this computer.
5. File>Transfer Purchases(To make sure all purchased content on her phone will be in her itunes library).
6. Right click in the device pane & select reset warnings.
7. Right click again and select backup.
8. Right click again & select restore from backup, select the backup you just made. When prompted to create another backup, decline.
9. This MUST be followed by a sync to restore her itunes content, which you select from the various tabs, You'll get a popup regarding her contacts & calendars asking to merge or replace, select merge.)
What do you guys reckon?
Thanks!

This is the process I would have recommended:
Backup your library using this User Tip.
Deauthorise the old computer if you won't be using it for iTunes.
Restore the library into the music folder on the new computer.
Install iTunes and sign in to your account.
For the "restore" process you can either just copy the backed up iTunes folder into the new computer or install and set up SyncToy to manage the transfer. If you install iTunes before restoring the library then you should delete/rename the existing empty iTunes library in your profile's music folder first.
Reconnecting an old iOS device backup set into a new iTunes installation is actually quite tricky, but provided the library has been properly conserved it is an unnecessary step. A library transferred as outlined above will be the same library the device was previously synced with, albeit on a different computer/operating system, and there should be no problem syncing media or apps. Info content such as calendar and contacts may need a little more care to make sure the same applications have as used previously have been installed and their data restored to them.
