!When the EF 70-200/2.8L USM is used with an extender, use the center AF point only. The other AF points may cause a focusing error. Page 85 There are additional notes for 24mm and 28mm lenses. This is curious, and I hope this doesn't apply to the IS version of the 70-200/2.8L. 
I've had no issues with the IS version of the 70-200 using several AF points. I don't have either of the other two lenses mentioned, but I did find it odd the outer focusing points are not useable with those two lenses.

re: Automatic Sensor Cleaning: Even if you repeat the sensor cleaning multiple times, the result will not improve that much. Sounds like common sense to me. Note that after cleaning once, the cleaning routine is automatically disabled temporarily. Page 132
The "Cleaning now" the manual speaks of is the functionality of selecting manual cleaning. However if the camera is set in the auto mode, the camera will repeatedly go through the cycle. For instance if one turns on the camera, the sensor cleaning begins automatically(if set that way), and then if I wait 1 second and turn the camera off, the sensor cleaning at power off does not occur. However if I wait 2 seconds and power off the sensor will go through the second power off cleaning. This obviously isn't something I would normally do but in the interest of testing it looks like the "temporary disabling" is quite temporary.

[C.Fn II-1: Long exposure Noise Reduction] During the noise reduction process, shooting is possible... With Setting 1 and 2, after the picture is taken, the noise reduction process may take the same amount of time as the exposure. During the noise reduction, shooting is still possible as long as the maximum burst indicator in the viewfinder is "1" or more. Page 163 This is interesting, as it may contradict previous implementations, though I'm not sure. I could swear I read about (and have witnessed) the same behavior on my 1Ds, though I have also read that shooting was not possible during noise reduction (for previous 1-Series cameras).
I thought this was due to dark frame comparison but I could be wrong as I haven't used that functionality, but it seems to me that was the case in previous models.
