Working with duplicates and combining files

Question

I'm new and trying to learn how to properly use Itunes. I am currently importing all my cd's onto an external drive (F Drive). Apparently after reboots ITunes sometimes imported the songs on the default C drive and not the F drive(which I did not realize until now). Now I know to change it back to the F drive when I reboot. My problem is that somehow I have copies of some of the albums on my C drive and some on the F drive as well as duplicates on both. Not sure what I did to get the duplicates. Here is my problem. For example, I have a folder of Brad Paisley on C drive that contains Mudd on the Tires, Time Well Wasted and Who Needs Pictures. On the F drive it only has Mudd on the Tires and Brad Paisley II. So I have one duplicate and one that wasn't on my C drive. I have a lot of folders in this manner. How do I go about getting ITunes to copy only the folders I need to transfer to the F drive? I did a try a couple and ITunes copied them and duplicated so many songs so now I have to go through them and delete them dups (which are hundreds!). I also tried to just drag them from C to F drive but it of course copies over the Brad Paisley folder and you lose some of the albums depending on which folder you pasted over. I was manually going through each folder and comparing them and dragging just the album to the F folder that was missing on the C drive. But this is taking forever. Is there a quicker way? Also is there a quick way to delete all the duplicates? And one more question, the F drive has most of my song with star ratings but the C drive does not have any star ratings. Is there a way to import and/or transfer the music without losing the star ratings I have? I'm working with about 10,000 songs so that is why these are such enormous tasks.
Sorry for the long explination. I just wanted to make sure I was being clear on my question. I hope there is an easier way and that someone will share their knowledge. Thanks so much.
P.S. Is there a book you suggest that will help me or is it best just to ask questions as they come up here? Thanks again.

Here is my code
var imageURL:String = "vid12.SWF";
var request:URLRequest = new URLRequest(imageURL);
uiLoader.scaleContent = true;
uiLoader.load(request);
progressBar.source = uiLoader;
progressBar.addEventListener(ProgressEvent.PROGRESS, progressHandler);
progressBar.addEventListener(Event.COMPLETE, completeHandler);
function progressHandler (event:ProgressEvent):void {
status_txt.text = int(event.currentTarget.percentComplete) + " %";
function completeHandler (event:Event):void {
progressBar.removeEventListener(ProgressEvent.PROGRESS, progressHandler);
progressBar.removeEventListener(Event.COMPLETE, completeHandler);
removeChild(progressBar);
status_txt.text = "";
