Remove photo noise

Making photos on a music festival is always a challenge. For easy manipulation I use a small camera with a 30x optical zoom. Lichting effects, smoke, loud bass sound vibrations, moving persons on stage and around you and in this case dark weather make it difficult to capture acceptable photos. The small sensor in this kind of camera can't give ultra sharp pictures, so sometimes I use gimp to correct some photos. In the result there is some lost of detail but I just want to look on my computer screen to 4896x3264 (180 pixels/inch) photos. That's right for me. To correct some photos, I used this filters in gimp (original photo 30x optical zoom)  :
Filters / Enhance / Wavelet-Decompose (value 7)
Set layers 'scale1' and 'scale2' on not visible
Make a new layer from visible (as a top layer)
Script-Fu / Sharpness / Sharper / High-pass Sharpen (colour / value 20)
Make a new layer from visible (as a top layer)
Script-Fu / Sharpness / Warp Sharp (values 7/3/2/2,5)
Filters / Enhance / Sharpen (Unsharp Mask) (values 2/0,5/0)
