to get my money back
Doubt that will happen as VMware Fusion comes with a free 30 day trial and one is supposed to take advantage of that to ensure it meets ones needs/wants before purchasing! 
I just want to rid my machine of all VMware and try to get my money back, so please help.
As to cleaning up have a look at 
Uninstall a Virtual Machine by Using the Virtual Machine Library or Uninstall a Virtual Machine by Using the Finder and Uninstall VMware Fusion.
Otherwise have a look at: Manually uninstalling VMware Fusion
Additionally you can use utilities like Disk Inventory X or GrandPerspective to look at the Macintosh HD from a graphical perspective to help isolate what's consuming all the space.
