Histogram in RGB
C.Fn 01 - Finder display on during exposure (1) Doesn't really matter
C.Fn 02 - Shutter release without card not possible (1) I've been burned a couple of times
C.Fn 04 - Generally AE/AF, no AE lock (3 though for certain situations I turn AE lock on (1)
C.Fn 05 - Shutter speed on back dial, aperture on top dial a holdover from the settings on my old 30D
C.Fn 06 - 1/3, 1/3 (0) for maximum flexibility
C.Fn 07 - Set to 0 but it doesn't matter as I don't own any electronic MF lenses
C.Fn 08 - ISO on top LCD, remaining shots on back LCD quick glance down to see my card status
C.Fn 09 - -,0,+/No cancellation (3) personal preference, though I rarely use bracketing
C.Fn 10 - Brighter (3) preference
C.Fn 11 - Default AF point selection (0) again, personal preference
C.Fn 12 - Mirror lockup off (0) unless I need it for a long exposure
C.Fn 13 - 11 manual AF points, spot metering slaved to active AF point (1) I generally don't need manual selection of all 45 points, and when I use spot metering, I prefer to meter on my focal point which is usually off center
C.Fn 14 - Evaluative (0) default, most of my flash is neither TTL nor on camera
C.Fn 15 - 2nd curtain sync (1) preference
C.Fn 16 - Safety shift off (0) I prefer the body not override my settings
C.Fn 17 - Expansion off (0) I prefer the quicker response and less tendency for the AF to stray
C.Fn 18 - Only while pressing "X" button (2) essentially a dual back button AF activation
C.Fn 19 - Stop button normal function (0) default, I don't own any glass with an AF stop button
C.Fn 20 - Moderate fast tracking (3) personal preference
C.Fn 21 - Servo priority enabled (1) sometimes I'll disable it with indoor sports or low light servo shooting to save buffer space

P.Fn 02 (on) - Evaluative disabled I don't use it

For shooting sports in AI servo, I'll usually have one back button set for portrait orientation, and the other for landscape orientation. If I'm shooting in one orientation, I'll leave the X button set to center high, and move the * button focus point to wherever I need it at the moment.
For shooting static subjects in one shot mode, I switch to automatic AF point selection unless I'm having difficulty or aiming for a specific focal point.
