comment Define area of study in Google Earth before Import in Qgis
I don't really understand your question? are you looking to make a polygon in Google earth and import it to QGIS? To do so, create a polygon in Google Earth and save it as a KML. In QGIS, click on add vector layer and add that KML file to your map.

Have you considered asking Google directly?

comment What is the best open-source web mapping solution for handling 3000+ polygons
Can you rasterize these polygons? or perhaps use a feature server such a geoserver or featureserver?

comment How to obtain road classification type at a point via nominatim?
I think road hierarchy is usually a jurisdictional manner in the true transportation sense. You're best bet is to contact your local transportation agency or the agency responsible for the data and get their GIS classification scheme + layer. I'm not sure about the UK, but in North America a lot of this data is available online for free.

comment Looking for a functionality in QGIS to find all neigbours in a polygon layer
@NathanW good point. I've never used spatialite. Feel free to edit or repost an answer using it and i'll delete my answer after that.

to add to @Llaves comment, perhaps look into shortest "Cost" where cost is a function of time, distance, $, and any other variable you would like to add to it

comment Help with Shortest path Algorithm for enormous bus routes database
If this is a transportation planning exercise, you're better off aggregating the stops into a multi-tier system going from more aggregate to disaggregate. The bigger zones tell you about regional traffic, then as the zones get smaller, you can tell more about traffic dynamics and patterns. Determining a Transit O/D (between each stop) is not that beneficial from the grand scheme of things

This is absolutely awesome.

@whuber Also, I have a smaller layer which is a subset of the road network where the equipment will go on.
