comment QGIS - Adding Raster Data to a Scanned Map
It's very difficult with scanned maps, because it's very unlikely that, for example, all of the pixels in the 'chalk' areas will have identical values. You can spend an awful lot of time trying to do what you propose. It might be quicker to trace the geology objects to vector polygons. N.

comment How can I import open street map power grid data into QGIS?
My apologies, I misunderstood the question and thought you were trying to extract the data you need from the OSM data set. You have a problem, if you can't get at the original vector data I think all you can do is download the JPG, georeference it and then trace the power network. N.

The shapefile is the native vector format for QGIS and if you have a decent one for the area of interest I'd suggest that QGIS is the way to go. If the shapefile is not confidential it would help if you could post a link to it.

comment No cadastral maps in the UK. Solutions/alternatives for a methodology?
I wonder if the new OS Open Map Local dataset might help? The buildings polygons are much better than we've had before, but with no data of course. ordnancesurvey.co.uk/business-and-government/products/…

comment Coordinate mix up
Bear in mind that you can set Google Earth to show UTM (projected) coordinates if required. These might be easier than lat/lon for you to work with.
