Rebel XT sensor cleaning

I bought my XT at a flea market for $30. The previous owners actually left a fingerprint on the CMOS itself, and I need to get it off for better night photography (with 654 sec exposure, it's clearly visible). I also need to clean the lens itself, and the camera has a function to lift the mirror. I know I need one of those hurricane bulb thingies, but how can I safely get rid of the fingerprints? There are also two large blurry black specks.
