HT1751 How do I delete a new itunes library I created on a new computer?

Question

I'm not the most literate computer person in the world so please bare with me.
This is the scenerio that took place.
I purchased a new computer. I have my complete Itunes library on my iphone from my old computer and wanted to just transfer library from iphone to new computer by syncing phone to new computer.
I did this but there seemed to be some things missing on my new computers itunes library.  I created a new library on my new computer which gave me 2 libraries. I basically did this to see if I could kinda just back up my original library in case I screwed up something. After I created new library, which is called NEW COMPUTER, I tried to get back to the old library to compare. Well now every time I open itunes on my new computer I cant figure out how to bring up the original library that I initially put on new computer.
I tried to uninstall itunes on new computer then reinstall and start over but for some reason when I open Itunes the new library I created is loaded.
All I basically want to do is transfer all my library items from old computer to new computer as easily as possible.

Here are the typical layouts for the iTunes folders:
The database that knows what tracks are in your library is the *.itl file.
The folder containing the database gives the iTunes window its name when you run it, so if your active library says NEW LIBRARY at the top then you are currently connected to ...\NEW LIBRARY\iTunes Library.itl.
Unlike most applications you can't just double click on an *.itl file to open it, iTunes will always open the last successfully opened database unless you hold down shift as you start to get the choose/create options.
Chances are your NEW LIBRARY has been created inside the normal iTunes folder. Once you've held down shift as you are starting iTunes, and have clicked choose, you probably need to find an up arrow button to move up one folder level to reveal the normal library.
