The command \footnote is really annoying me. I have to use hacks to use it in section headings, epigraphs, tables, minipages and whatnot.
Can it be fixed? Has someone already implemented a footnote command that Just Works™?

Your error is produced by the following MWE:
\documentclass{article}
\usepackage{hyperref}
\begin{document}
Test\footnote{Footnote text.}.
\begin{table}[t]
\centering
\begin{tabular}{cc}
First & Second\footnote{Second footnote.}
\end{tabular}
\caption{Caption}
\label{tab:t}
\end{table}
\end{document}
this time with reference to {HFootnote.2}. The .2 means that is the second footnote causing the problem. Cutting and pasting your other code in does not produce the error your report from the table with a \parnote. So try to track down direct uses of the \footnote command in your document.
hyperref has all sorts of issues with footnotes. See the answers to the question Clickable Table Footnote, for discussion, why not to do this, and workarounds.
To get the footnote number as superscript use \textsuperscript{\ref{<label>}}. The link box provided by hyperref is not easy to tweak with, but in Adjust box around hyperref footnote links there is a solution to make all boxes fit the number tightly.

To get footnote in headings you can use either
footmiscor simply the option argument of\section[without footnote]{with footnote}. But I agree with the comments claiming that one shouldn't use footnotes in a section heading.With
minipage(andtabularand\parboxand even\mbox) the problem is that they trap the footnote. You can either use\footnotemarkinside such boxes and\footnotetextoutside, or you can use thefootnotepackage which offers a lot options to help footnotes escape E.g.See also the FAQ: http://www.tex.ac.uk/cgi-bin/texfaq2html?label=footintab.
