GIMP is also available for other platforms, including Windows. But I think it's a bit too much for such a simple task. I'd recommend programs like XnView or the Faststone Image Viewer. These are very versatile and useful tools not only for digital photography.

Centimeters or inches only make sense together with an adjusted dpi setting (pixel size = size in inches times relative resolution in dpi). Which may be a bit too much for a beginner trying to scale a picture. I'd strongly recommend using absolute dimensions in pixels. For instance 1000 pixels width or height, whichever is greater. The other dimension usually is set automatically according to the aspect ratio of the image.

Dito. However, what one software calls "60%" may be "8 out of 12" or "7 out of 10" in another program. ;-) BTW XnView and the Faststone Image Viewer have very effective JPEG algorithms, so the size/quality ratio is quite good there.

I'd finally recommend removing all metadata and have the file optimized. This can be done with various programs, including the two mentioned above. Real cowboys may do this with a command line utility and lots of cryptic options. ;-)
