The command \twocolumn[<foo>] starts a new page and puts <foo> in a
one-column box at the top of the page. If you were to specify the
header exactly as you want it as the optional argument to \twocolumn,
you would get what you want. But

\twocolumn[\maketitle \begin{abstract} <text> \end{abstract}]

does not work because the \maketitle command invokes \twocolumn
itself (thereby exiting single-column mode before getting to the
abstract), and the abstract environment formats itself for two
column printing. To automate what you want, put the following in a
style file:

\def\abstract#1{\def\@abstract{#1}}
\def\@maketitle{\newpage
 \null
 \vskip 2em \begin{center}
 {\LARGE \@title \par} \vskip 1.5em {\large \lineskip .5em
\begin{tabular}[t]{c}\@author
 \end{tabular}\par}
 \vskip 1em {\large \@date} \end{center}
 \par
 \vskip 1.5em
\small
\begin{center}
{\bf Abstract\vspace{-.5em}\vspace{0pt}}
\end{center}
\quotation
\@abstract
\endquotation
\vskip 2em
\gdef\@abstract{}}

This just puts the abstract into the \maketitle macro, so that it
is set within a \twocolumn[] command by \maketitle. Instead of
using the abstract environment, put

\abstract{<text>}

in the preamble. Then make your title with \maketitle right after
begin document (without using the \twocolumn command), and you are
on your way.

I didn't modify the setup of the title, but personally, I find the
extra space at the top of the page and the extra large title to
look lousy at the beginning of a two column document. I would change
\vskip 2em to \vskip -2em, for example.
