Windows 7 Disk Management problem after using WET

I am an idiot who knows just enough to mess up my computer! Now I am turning to you all to save me from myself.
I used Windows Easy Transfer to move my files from my old Dell laptop running Windows XP to my new Inspiron 1764 running Windows 7 Home Premium 64-bit. The problem I ran into is that my new files seemed to be on one partition and another one contained all the empty disk space of my new computer. I tinkered and managed to delete the operating system. I tinkered again and repaired it. But I still can't expand my C: partition and of course I am being told I have very low disk space. I only have the option to "shrink" and when I try that, it tells me I have 0 space to shrink. I'm afraid of making another really big mistake since in truth, I really don't know anything and reading about disk management and partitions has not enlightened me. I would be very grateful for any help so that I can get access to the free space. Two screenshots are attached. Thank you.

Thank you, thank you, thank you! I had been worried about deleting anything again after my last fiasco of trying to fix this myself but following your directions solved the problem and I now have my whole hard drive to fill up! Very grateful!
