3. How to stop the second line being justified out to the right?
In the fuller score, something like this is followed by a page
break and more music, but there is a natural break at this double
bar, and it looks very "stretched out". I tried various "ragged"
keywords, but none of them just operated on the one line.
Is this not what you want?
\paper {
ragged-last = ##t
}
That works for the last line of the whole score. The line I want to be
"ragged" is the last line of a page. with more music on the next page.
A similar question last year got several answers:

If you want to try pseudoIndent, I have appended the latest version.

PSEUDOINDENT FUNCTIONS
% these two functions are for indenting individual systems
% - to left-indent a system, apply \pseudoIndent before the music continues
% - \pseudoIndents is similar, but lets you also indent on the right
% - both provide an option for changing that system's instrument names
% N.B. these functions
% - assume application to non-ragged lines (generally the default)
% - include a manual \break to ensure application at line start
% - misbehave if called more than once at the same line start
% the parameters of the (full) pseudoIndents function are:
% 1: name-tweaks
% usually omitted; accepts replacement \markup for instrument names
% as an ordered list; starred elements leave their i-names unchanged.
% 2: left-indent
% additional left-indentation, in staff-space units; can be negative,
% but avoid a total indentation which implies (unsupported) stretching.
% 3: right-indent
% amount of right-indentation, in staff-space units; can be negative.
% - not offered by the (reduced) pseudoIndent function
pseudoIndents = % inline alternative to a new \score, also with right-indent
