disabling start up programs

I have used spybot to disable some programs that automatically start when i log in. I wonder if someone would care to peruse the attatched list and comment on those programs still starting at start up.

Please note that although this entry below says disabled I get a spybot message to tell me spybot is unable to make changes to this program

with regard to the system files I have no clue as to wheather I need these running or in fact what they do. I have highlighted the entries I dont know about.
If you can advise please do so.
