Here are my comments to your configurations - I've deleted lines that I don't

Why not just add the directories to the path initially? I set all environment
variables in /etc/environment and play some tricks so it can be read from
bash-like shells as well as csh-like shells. I do the same for ~/.env.
This way there is one and only one location for system-wide environment
variables and one and only one place for user-specific variables.

I've tried running the fllowing from login and non-login shells

The results have always been the same - are we using the same terminology?

Here's my PS1 line from /etc/environment:
${_envcmd_} PS1${_enveq_}"\[^[[33;[EMAIL PROTECTED]: "
Where bash-like shells set:
_envcmd_="export" & _enveq_="="
While csh-like shells set:
+envcmd_="setenv" & _enveq_=" "
Note: The "\[" and "\]" are bash specific escape sequences that 'hide" the
enclosed characters so they aren't counted in determining the cursor's location.
a better explanation is included in bash's man page. To be honest, this
PS1 should be set in a bash-specific location until such time as I can get
tcsh to handle color prompts...

I think that 002 is a fine umask for all users - Debian handles groups in
such a way as to make twiddling umask values unnessesary. BTW, I'm paraniod
and have umasks of 007 for the default.

I typically use --color=always...or at least have been for the past couple
of weeks...

Setting the '-r' option on less allows for paging color output.
Try this command:
bash > ls -l --color=always | less -r
When I do this I get paged color output...YMMV.

Is there a better way to determine whether or not their shell is a login
shell or not? This seems akward at best...though I'm not convinced that
it's all that needed...

Looking at that line again, I'd say try adding "{" and "}" around your
variables, like this:
PS1='${ESC}[${COLOR};37;1m${USER}:${ESC}[37;40;1m\w\# '

BTW, I also set the following for xterms:
PROMPT_COMMAND='echo -ne "\033]2;$TERM: [EMAIL PROTECTED]:/$PWD/
\007\033]1;$PWD\007"
This changes the title bar of my xterm to show user, host and cwd.
