How do I refer to a footnote? For example, if is constructed like this
blah blah blah blah\footnote{blah blah \label{footnote_1}}
would you refer to it using this line?
As mentioned in note \ref{footnote_1}.

You can use \mytag{<tag>}{<label>} as defined in the following MWE:
\documentclass{article}
%\usepackage{amsmath}% http://ctan.org/pkg/amsmath - loaded by {mathtools}
\usepackage{mathtools}% http://ctan.org/pkg/mathtools
\makeatletter
\newcommand{\mytag}[2]{%
\text{#1}%
\@bsphack
\protected@write\@auxout{}%
{\string\newlabel{#2}{{#1}{\thepage}}}%
\@esphack
}
\makeatother
\begin{document}
\begin{equation*}
\sum_{i=1}^n (i + i^2) =
\underbrace{\sum_{i=1}^n i}_{\mytag{A}{termA}} +
\underbrace{\sum_{i=1}^n i^2}_{\mytag{B}{termB}}
\end{equation*}
\newpage
Later in the text, I want to talk about term~\ref{termA} and term~\ref{termB}.
\end{document}
You supply the <tag> you want to put down for the label, as well as the regular label <label>. \mytag prints <tag> using \text{<tag>} (from amsmath) and then performs the regular label-writing to the .aux file (taken from latex.ltx). That allows you to use \ref{<label>} to retrieve <tag> again.
Note that this does not support usage with hyperref. Modifications are required in order for that, but it is doable. Wait for it...
...and now with hyperref support:
\documentclass{article}
%\usepackage{amsmath}% http://ctan.org/pkg/amsmath - loaded by {mathtools}
\usepackage{mathtools}% http://ctan.org/pkg/mathtools
\usepackage{hyperref}% http://ctan.org/pkg/hyperref
\makeatletter
\newcommand{\mytag}[2]{%
\text{#1}%
\@bsphack
\begingroup
\@onelevel@sanitize\@currentlabelname
\edef\@currentlabelname{%
\expandafter\strip@period\@currentlabelname\relax.\relax\@@@%
}%
\protected@write\@auxout{}{%
\string\newlabel{#2}{%
{#1}%
{\thepage}%
{\@currentlabelname}%
{\@currentHref}{}%
}%
}%
\endgroup
\@esphack
}
\makeatother
\begin{document}
\begin{equation*}
\sum_{i=1}^n (i + i^2) =
\underbrace{\sum_{i=1}^n i}_{\mytag{A}{termA}} +
\underbrace{\sum_{i=1}^n i^2}_{\mytag{B}{termB}}
\end{equation*}
\newpage
Later in the text, I want to talk about term~\ref{termA} and term~\ref{termB}.
\end{document}
As it stands, these two methods are exclusive. That is, if you want hyperref support, the second approach works. If you do not want support for hyperref, then you should go with the former.
It does not matter, that \label is hidden in a \newcommand. For referencing you need the label name that depends on the second argument of \graphPairs. The first example would be generated by:
\graphPairs{``Here's a question?''}{4}
And the labels can be referenced by
\ref{fig:4-byVar1}
\ref{fig:4-byVar2}
\ref{fig:comboFig-4}
