Let's see:
OsaFindFast is a Microsoft Office "find forms fast" auto-indexer. You can remove this.
StiMon is the Windows component that monitors the scanner (or other image capture device), and any buttons you may have on your scanner, to see if it should interface the device to TWAIN. Assuming you aren't capturing images during flying, you can disable this.
QTTask is the Quicktime monitor in the taskbar tray. You can DEFINATELY remove this.
I don't recognize the others, but you can always Google them and see what they are.
