Get a faster lens
OR
use more light
OR
use noise reduction software in post
You can gain one stop of light by overriding the shutter speed to 1/25sec. (But be aware of some motion-blur)
Try to expose such that the highlights are just below clipping (RAW-Histogram).
I tend to use ETTR on the brightest Part of my Scene to optimize exposure before each shot.
For Noise-Reduction NeatVideo works great. It uses also temporal filtering so you do not loose as much detail as by just the ACR Noise reduction. But the differences are not huge.
ISO 800 is the last useful (http://www.sensorgen.info/CanonEOS_7D.html) ISO on the 7D. So unless you can increase exposure (through shutter/aperture/scene luminance), then your SOOL.

I agree I never used anything above ISO 800/1250 on my 7D.... and in your last picture besides the fact the not a single thing is in focus I see no noise.
1250 is a digital push of 800. So in this case, it's probably better to do the digital push in post so that you retain the 1/3 stop highlight detail.
When it's pushed digitally in camera, it simply clips the top end.

On this point, noise helps to increase the perceived sharpness of detail. Where there is lack of detail, such as in areas of the frame that are out of focus, the noise becomes entirely problematic.
