Please note, as I am busy with a full time GIS job, I cannot guarantee responses to queries but I will try if I have time :)

This channel offers rapidfire (sometimes 1 minute!) videos showing specific features of GIS related software ESRI, OpenSource, MapInfo and even games platforms are all covered.

Make sure you subscribe to these free hints and tips that could greatly improve your GIS workflows.

I often use OpenData too, so I will be pointing you in the direction of lots of free data as well :)
