Have you tried using a lint free cloth? Not sure what your brown film is, but if it's mostly dirty brake fluid residue, it should wipe out. Don't use gas or any other solvent on the cloth. You don't want to contaminate the system with a foreign fluid. You could put a few drops of clean brake fluid on the cloth if it doesn't want to come off with the cloth alone.
No, you don't have to bleed the fluid completley out, and I don't recommend doing so. Make sure the level stays at the top of the hose or a little higher so you don't get bubbles in the line. I'm assuming you are going to add fresh fluid to the entire system once you have cleaned the mc, correct?
I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
