comment Load .osm.pbf file in Qgis
This is the way I do it. The ogr configuration file osmconf.ini can be edited to select or deselect the OSM keys that will be reported as fields in the database.

comment How to apply colour ramp to user-defined range of values for contour lines?
My crude way of doing this would be to merge all of the contour shape files to one, apply the required style and then save the style as a QML file.

comment Why do each of my buffer-polygons have different areas
Grass v.buffer.distance is available from the QGIS Processing Toolkit, you won't need to go into GRASS to use it.

I should have a look at the MultiQML plug-in, which allows one QML style file to be applied to multiple vector layers in one operation.

I'm not sure I fully understand the question, but I think you will need to merge the contour tiles into one big shapefile and style this.

comment DB manager not updating
Probably best to use the QGIS Browser to "delete" spatialite databases that no longer exist. Also, make sure database names are unique.

comment Can't transform lines to polygons
Actually, what you did was very sensible. ogr2ogr (used in QGIS via "save as..") is good at repairing some sorts of broken shapefile.

GRASS and I don't get on either, but you can use these functions within QGIS: Processing -> Toolbox.
