my ocd has reached new levels
Go here if you want to modify read-only icons :) which you can find here. Dock spacers are here.
See updated version (July 10, 2012).
ps the updated version is out of date because now I am running Mountain Lion and I don’t use Bartender anymore (September 10, 2012)
stream of consciousness 
you should check out a little program called Bartender, it’ll make your menu bar look much nicer.
thanks! will do!
