Yours are well thought-out questions. I believe the answer to most
of them is yes. Overall, you appear to have typesetting concerns
similar to mine, which suggests that groff and the latest version
of the mom macros will give you about 80% of what you're looking
for.
Please bear in mind that your concerns are most likely less "what
groff can do" than "what a particular macro set does natively."
Anything a macro set doesn't do you can usually make groff do,
either at the "primitive" level, or, more commonly, by writing your
own macros to fill up the deficit.

Color using CYMK is possible in groff.
The mom macros handle it with
.NEWCOLOR \" defines a color by name (user choice) and CMYK values
.COLOR \" sets subsequent text in the named color
The inline escape \*[colorname] does the same thing as .COLOR

I find groff's font installation quite straightforward. See the
mom documentation on the subject at
http://www.golden.net/~ptpi/appendices.html#FONTS
The article is written with an eye to groff newcomers.

Yes, this is possible with groff, although it requires user
intervention. I don't know of any macro set that automatically
hangs punctuation when it occurs at the end of a line. If you
require that functionality though, I believe it's possible to set
it up.

I'm not sure what you mean by "multiple" series.
A number of macro sets, including mom, have footnote capabilities.
I suspect their handling in mom, which is pretty sophisticated, is
what you want.
Margin notes is a subject that came up recently on the list.
Werner has written macros to handle them (available from the groff
repository, I believe). I have yet to incorporate his ideas into
the mom macros (time, time, time!), and I'm not sure how well
Werner's macros integrate with other macro sets.

Yes, this is possible with groff.
The mom macros handle it with
.RW \" Reduce inter-letter Whitespace by a specified uniform amount.

If I understand what you want, the mom macros handle this with
.SHIM
SHIM simply inserts the amount of space required to make certain
that your next line of text falls on a "legal" baseline, i.e. on
a baseline grid.

Groff has the .PSPIC macro (man groff_tmac), which can be used
with any macro set, to import PostScript graphics. Groff doesn't
natively handle other graphics formats like TIF and BMP, so your
graphics have to be converted to PostScript first.

To the best of my knowledge, people have discussed the theory but
no one has, as yet, implemented it.

The mom DROPCAP macro allows almost all the tweaks you want, except
sloping indents and protruding serifs.

I'm not sure any existant macro set does all this automatically,
but I'm certain it's possible.

I don't believe groff can do this, but someone else may know
better, or have a workaround.

Each macro set with footnote capabilities handles this differently.
In the mom macros, if a footnote reference occurs in the last line
on a page, the footnote itself is moved to the next page, with
the "marker" (star, dagger, number, whatever) picked up from the
previous page. If the footnote reference also happens to be the
first footnote on the page AND the page the footnote is moved to
also has footnotes, the "moved" footnote is separated from the
footnotes proper to the page it's moved to by whitespace. This
visually resolves any confusion that might occur when, say, the
footnotes contain two entries that are both marked by a star (the
usual "first" footnote marker).
Alternatively, the mom macros can number footnotes incrementally
throughout a document, in which case there's no confusion.

Hopefully, others will add to what I've said and answer all your
questions.
