I have a paragraph as follows:
``This is a quote. `Here is a quote within a quote.'''
But the formatting works out to be a double quote (") followed by a single quote (') instead of the other way around. How can I solve this problem?

You have the following options:

Outer double, inner single: ``\thinspace`\ \ldots\ '\thinspace'' \par
Outer single, inner double: `\thinspace``\ \ldots\ ''\thinspace'
The TeX Book mentions (Chapter 2: Book Printing versus Ordinary Typing, p 5): "There's usually less space preceding a single left quote than there is preceding a double left quote. (Left and right are opposites.)"
So, in your instance,
``This is a quote. `Here is a quote within a quote.'\thinspace''

\`{}`Foo'{}''` be an option as well? It's kinda hard to tell, but the spaces do differ a bit between the "black marks" in the output. Considering you're quoting Knuth's recommendation, it doesn't seem to be what was intended by the inventor.

The csquotes package might be helpful.
For nested quotings just nest \enquote{} like this:
\documentclass[english]{article}
\usepackage{csquotes}
\begin{document}
\enquote{outer and \enquote{inner}}
\end{document}

It is also very useful for non-english quotation marks:
\documentclass[naustrian,german]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage[babel]{csquotes}
\begin{document}
\enquote{außen und \enquote{innen}}
\end{document}

\enquote{innen}.}, perhaps even \enquote{innen}}.. (On a side note: Why not use the minimal class)

\documentclass{article}
\begin{document}
``` ''' % misinterpretation by (La)TeX
``{}` '{}'' % good interpretation (but bad spaces)
\end{document}
An alternative solution is use the \, command. It'll give you an output similar to the method using \thinspace.
Example:
``This is a quote \,`Here is a quote within a a quote.'\,''
\, is defined exactly as \thinspace if not in math mode. And it's convenient to type, and the LaTeX documentation gives a similar example.
