Are you sure? I never need the line numbers, because Emacs (gud)
takes care of them and shows me the current line automatically. For
setting breakpoint, go to the source file and then C-x SPC.

B'cos environments are inherited by child processes from their
parents. When you start the gdb process from gud/Emacs, it of course
inherits the environment of Emacs.

(setenv "FOO" "BAR")
(getenv "FOO")
I often do these in the *scratch* buffer (lisp-interaction-mode).
Just type one of the above and then C-j.

It depends on the terminal-emulation package that you're using. Emacs
has so many. RTFM.
A quick check is to run the 'env' shell command and redirect the
output to a file. Do this both in a vanilla shell and a shell running
under Emacs. Then, use 'diff' to check what are different.
