OK, I got somewhere - except the I cannot get the plots' combined width to fit within the margins (hope someone will offer a solution for that):
Otherwise:
- Aligning the xlabel, ylabel: is a bit of a pain; note the manual states:
The starred versions . . . line* only affect the axis lines, without correcting the positions of axis labels, tick lines or other keys which are (possibly) affected by a changed axis line.
which in this case means that I should first set axis y line=middle to set the label position as I want it, then re-set with axis y line*=left afterwards, so only the axis position changes (this also adds the 0 as ytick label)
the zero to appear as first x axis tick label on the left-hand plot - similarly, by "overloading" with axis x line*=bottom
the zero to disappear as first y axis tick label on the right-hand plot - somewhat tricky, but seems that only thing that works, is "overloading" yticklabel and setting a conditional command via \ifnum in there, that uses \ticknum (which apparently starts from 1).
the axes tick label font - the problem is that by default, pgfplots typesets axes tick labels in math mode; as example - I've left the yticklabel overload so it typesets the number directly, and it can be seen it is in Times. Otherwise, Change font also on axes in pgfplots explains that an additional package has to be loaded to use Times as math font, and for me \usepackage{txfonts} works (though I bumped in the problem described in Local font installation problems, and the solution there worked for me).
auto xshift of scope: a similar problem is noted in pgfplots - Positioning a tikz scope relative to another tikz scope. This is not quite auto, but I use half of \textwidth minus half of intended separation to set the width of a plot; as it can be seen from the image, it's almost there but not quite right with the margins; will probably have to test the suggestion of @JohnKormylo, too
And here is the code:

You can use
y filter/.expression={y==0 ? nan : y}
in the options of \addplot.

See two marked bits (otherwise the tic labels are set in math mode by default)
