On your system there seems to be no difference between the two; one always sources the other if it exists. On my system, .bashrc is always sourced when I login, but .bash_profile is skipped for noninteractive shells.

Like I said I am using BASH on a Mac running Leopard. For the most part I use Terminal for my command line related work. However, sometimes I use X11 as well. I noticed that when i typed "echo $PATH" in a Terminal shell it returned a different series of directories than when I did the same in an X11 shell. I believe this is because those two programs check different environment files. Is that correct?
Maybe. I've noticed that Apple sometimes customizes these things in odd ways.

A user in a different forum suggested that I modify my .bash_profile and .bashrc files. Can you tell what exactly is going on? Here are the contents:
Please use code tags for code. like [ code ] asdf [ /code ] except without the extra spaces.

Code:
# Checks if the ~/.aliases file exists;  if it does, sources it.
if [ -f ~/.aliases ]; then
. ~/.aliases
fi

# Something to do with file size limits.  Mine doesn't have -Ss, so see
# 'man ulimit' on your system..
ulimit -Ss unlimited

# Includes some mac-specific environment variables, perhaps
source /Users/msb65/seadas5.2/config/seadas.env

Code:
# If .bash_profile exists, source it.
if [ -f ~/.bash_profile ]; then
. ~/.bash_profile
fi

SURFRAW-UPDATE-PATH(1)					User Contributed Perl Documentation				    SURFRAW-UPDATE-PATH(1)

NAME

       surfraw-update-path - updates PATH in shell config files

SYNOPSIS

       surfraw-update-path [-add] [-remove] [-check] [-sys] [-all] [-help] [-shell=SHELL]

DESCRIPTION

       surfraw-update-path adds the surfraw elvi directory (/usr/lib/surfraw) to your PATH in your shell's config file.

       Currently it supports bash, sh, csh, tcsh, ash, dash, ksh, pdksh, zsh, rc, and es

       Don't forget to login again or source your login files for it to take effect.

OPTIONS

       -check
	   Checks to see if the surfraw config code is present.  This is the default.

       -add
	   Adds the surfraw config code.

       -remove
	   Removes the surfraw config code

       -sys
	   Updates the system-wide shell config instead of the user.  Must be done as root.

       -shell=SHELL
	   Selects the shell to configure. Defaults to the value of the $SHELL environment variable.

	   Currently supported shells are:

	   sh, ash, bash, dash, csh, tcsh, ksh, pdksh, zsh, rc, and es.

       -all
	   Attempts to configure the startup files for all known shells

       -help
	   Gives a usage message

RETURN VALUE

       -check returns 0 if the surfraw code is present in the file, 1 if it is not found, or 2 on error.

       All other options return 0 on success, or 2 on error.

ENVIRONMENT

       SHELL
	   Used to determine which shell to configure, if -shell is not given.

       HOME
	   Used to find users config files.

       ENV Used by posix-compliant shells to specify a startup rc file.

       ZDOTDIR
	   Used to find user config files for zsh. If not set, defaults to HOME.
