"I dont think Ive ever had the windows malicious software removal removal tool show its results log after running, which its supposed to.."
The removal tool only displays a message when it detects and removes malware.
"It does install, and would state that it has installed successfully, but I wasnt 100% sure if it was supposed to run immediately after that or not"
The MRT doesn't install as such as it's a standalone scanner that specifically targets current threats. It runs just once. The following month a new version of MRT is released.
"Results Summary: No infection found. Microsoft Windows Malicious Software Removal Tool Finished On Wed Sep 28 11:30:07 2011"
Looking at your report, it clearly shows that MRT ran and found no threats. I can't seem to find anything useful regarding the "errors" that were mentioned. I've just checked the log on two PCs here and get the same as you so it's probably nothing serious.
