First, I would suggest changing the log format slightly to:
2011-03-14 13:28:00
Id="1657"
ApplicationId="My Test Application"
Severity="INFO"
User="George"
UserContext="Server5\George"
Message="File: C:\temp\MyFile.txt Deleted"
...
...
secondly, to specify a sourcetype for your data you can then edit inputs.conf to:
inputs.conf
[tcp://12345]
sourcetype = SomeName
