I'm not a .bashrc guru, but here's where I turn:

1. https://wiki.archlinux.org/index.php/Color_Bash_Prompt

2. http://wiki.gentoo.org/wiki/Bash

3. For a good short introduction of prompt basics for all shells,
http://www.understudy.net/custom.html

4. The "prompting" section of the bash manpage for an explanation of the 
arcane symbolism of the bash prompt string syntax

As to the line 16 and 18 variables, I don't find them useful unless
you are setting up a lot of different users.  Otherwise, to me,
they just add an unnecessary layer.

Here's mine:

PS1="\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] "
export PS1

Enjoy!
