rules
I am trying to add a horizontal line in my document.
\documentclass{report}
\begin{document}
\begin{center}
\Huge CV
\end{center}
\line(1,0){250}
\end{document}
For some reason, \line(1,0){250} will generate a line that is unequal on your document. What I mean is that the line will appear to be a lot longer on the right than the left. I am tryng to make it long and even. I also want to try to make it thicker if possible.
The rule added by the casual theme uses the following code:
{\color{color2!50}\rule{\textwidth}{.25ex}}%
Adding \par on either side allows for vertical spacing between document elements. The casual theme actually uses something similar to
\\[-.35em]{\color{color2!50}\rule{\textwidth}{.25ex}}\\[1.25em]%
to insert space above and below the horizontal rule.
I've added the above \par-suggestion inside a redefinition of \makecvtitle - the macro that creates the CV header/title - from the classic theme. It is clearly marked as follows:
{\par\color{color2!50}\rule{\textwidth}{.25ex}\par}% <----- ADDED RULE

%% end of file `template.tex'.
You may want to modify the spacing, if it doesn't suit your liking. Also, you may have to modify \makecvtitle further if you actually include an image.
Addressing only item 4, hiding the tabular inside a macro \logicarg{<premise>}{<conclusion>} might be more appealing:
\documentclass{article}
\newcommand{\logicarg}[2]{% \logicarg{<premise>}{<conclusion>}
\begin{tabular}[t]{@{}l@{}}
#1 \\ \hline #2
\end{tabular}%
}
\begin{document}
\begin{enumerate}
\item \logicarg
{If you are eating soup then I am happy. \\ You are eating soup}
{I am happy}
\item \logicarg
{If it is Wednesday then you aren't taking a quiz. \\ It is not Wednesday.}
{You are taking a quiz.}
\item \logicarg
{Either you love logic or you hate it. \\ You don't hate logic.}
{You love logic.}
\end{enumerate}
\end{document}

You could use the command
to get a line that spans the width of the text block. The following, very slight, modification of your MWE
generates:
Interestingly, it does not appear to be necessary to place the
\hrule(or equivalent) command inside thecenterenvironment.
