As far as I know, a command like \hline can come _after_ an end-or-row command (\\) but not _before_ one. What are the results of simply typing the following?:
\begin{tabular}{c | c | c}
A & B & C\\
\hline
F & F & F
\end{tabular}
Often it pays to try to get used to the appearance of the "standard" results, rather than hacking... But you could try, perhaps:
\begin{tabular}{c | c | c}
A & B & C\\
\hline
\multicolumn{3}{c}{}\\[-12pt]
F & F & F
\end{tabular}
After the \\ the program expects a new table row; it starts trying to typeset one (hence the vertical line at the end of what should have been the first cell of that row); to overcome this you'd need to define a "dummy" row, as I did with the \multicolumn command above, then add even more negative leading [12pt] or so, instead of [9pt]. But again, what's wrong with the standard tabular results?
Can't help with the other problem I'm afraid,
but...
