An appendix about a minimal installation is a far cry from a
full-blown documentation of those programs.  I agree that it would be
nice to have such guidelines somewhere in the docs.

Nothing is critical to tty colors except the Emacs binary.  The file
tty-colors.el is preloaded, and the rest of the support is in C and in
other preloaded files.  Even rgb.txt (the one which comes with the
Emacs distribution) can be nuked, since tty-colors.el has its own
copy of the X colors.

It tells Emacs which functions are preloaded; this is important for
some documentation features you don't want to lose.

What failure is that?  If colors don't work, check out the PROBLEMS
file, it has an entry about such problems.

Strip the binaries, especially the Emacs excutable: that would
release a few MBs.  But that comes at a price: you won't be able to
produce any useful information if Emacs crashes.

Yes, definitely.  But you should at least keep the file(s) in
lisp/term/ which are loaded by your terminal (look at the TERM
variable and then look for the file by that name in lisp/term; it
might include other files as well).  Color support doesn't depend on
these files, but special function keys support does.
