Yes, the effect penetrates through walls. The 70% or so of the people who can consistently feel the effect report being able to sense it passing through all materials, with one exception: lead. A thick (1/4" or more) sheet of lead seems to stop the "beam" from the device.

Nothing you come into contact with on a daily basis would cause problems (magnetic clasps on cellphone cases, etc...). For some larger magnets if there is a 2-axis compass it will not read correctly however it will have no effect on the GPS data or supporting electronics

I have two metal magnets crazy-glued to the bottom of my Garmin which when in use sticks to the two metal magnets I have hidden in my car's dashboard. I have been using it for years and they have not interfered with the signal.

Dont think so...

Some gps devices come with magnets at the base to be mounted on a metal object.

No, GPS uses microwave/radio signals which are unaffected by magnets.
