Skip already gave no-cost answers for 2).

Can you repeat 3)?  Are you just looking for images of maps of
the US, all its states, and all its counties, or are you saying
you want photographs ("graphics"?) from each jurisdiction?  If
the former, yes, fee-free versions of all those maps are avail-
able on the Web.  When I've worked on this before, I found it
entertaining to draw my own maps; I had enough data from the Web,
and the Tk canvas is handy enough, that it didn't take long to
program this.  I only did it to the state level, but counties
surely are equally feasible.  The Tkinter canvas has performance
limits that constrained the resolution I was willing to use ...
