Bootcamp, running into multiple issues....

Question

As a little bit of backstory, I bought a MacBook (late 2009 edition with Snow Leopard) because I was having issues with my old Windows XP PC desktop, which was invaded with trojans and viruses. I had to delete everything, start up from scratch and wipe the disc clean. Not pleasant.
In the summer of 2010 I was convinced to buy a Macbook because it didn't need to be checked quite as often as a PC computer. I was astounded by the speed in which it booted up since I never had a custom built PC that contained optimized performance. Mostly however I had only used the Macbook as a means of searching the web and to use it to complete college assignments.
It wasn't until last year that I decided I wanted to get Windows onto my Mac, but being unemployed and with no job, it was simply not an option, because I needed to get bills done on time. Fast forward to this year, and after months of frantic job searching I finally landed a job. Now with a steady income coming in I felt it was time to get Windows onto my Mac.
Sadly it's easier said than done. I wasn't even aware of Mountain Lion and Mavericks until later this year, but I realized that upgrading to those systems required more than a simple DVD disk.  Since then it's been a obstacle course, and while I've done a lot of research on bootcamp files for the various Mac versions, there is still lots I don't know about. Which leads me to this problem.
Since my Macintosh HD drive only holds 250 GB, I felt it was needed to get rid of some used space. After deleting various games that were left untouched the last couple of years, I have 150 GB of free space. Problem is, I cannot partition. Why? Because some OS X files cannot be moved.
So I bought a Windows 7 Home Premium 64-bit disk off of Amazon, and when I realized I needed a Snow Leopard installation disk, I bought that too. I now just spend between $140-150 in software, which isn't too bad I guess. Turns out that the Macintosh HD drive was corrupt, so I restarted the Macbook using the Mac OS X installation disc to access Disk Utility. After verifying and repairing disk (I got the confirmation from the green text), I assumed I can partition. Nope. Same issue pops up. So I realized I needed to get rid of free space, so I run Disk Utility off of the operation system and used the delete free space (zero) option. After a hour it's finished. Make another attempt at partitioning. Failed.
Now I don't know what to do. The steps involved require an external drive and an internal drive, along with a program named Carbon Copy Cleaner (CCC). So what am I supposed to do? There are options to unmount and make new disc images on Disk Utility, do I just run that and go from there? I'm very confused at the moment.

This would of been nice if I had known all of this before I even attempted to make a partition, so now I need an external hard drive to get past the problem of the Mac OS X files not moving. I thought I only needed a Mac installation disc and the Windows 7 install disc but it turns out I was wrong.
As for external hard drives, Seagate Backup Plus (1 TB) looks pretty good, that's more than enough to make a backup. I spent the past few days doing a lot of research on bootcamp. Since the Mac installation disc is actually 10.6.3, I may still have to have the bootcamp drivers (versions 3.1-3.3) to install onto the Windows partition, along with Apple Software update so the features actually work with Windows.
Very frustrating, costing me over $210 just to try to partition, if this doesn't work then I know it's a bad hard drive. Probably will have to take the Macbook in to an Apple store and have them look at it. The external hard drive itself will be good purely for backup. I have to wonder if all this is simply worth the trouble, considering I've toyed with emulators in the past, which tend to fail on occasion.
Repaired disc, erased free space in disc utility, etc. So I guess I have to wait.
