For the first half of your question:
I think your left and right margin were in fact already of the same size, the problem is, that the sum of all your columns and spaces was bigger than the available space, so that the left side was intruding the margin.
You can try and add \begin{columns}[t, totalwidth=\textwidth] and modify the size of your columns via editing \setlength{\onecolwid}{0.20\paperwidth} etc.
\documentclass[final]{beamer}
\usepackage[scale=0.78, size=a1]{beamerposter}
\usetheme{confposter}
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70}
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10}
%-----------------------------------------------------------
\newlength{\sepwid}
\newlength{\onecolwid}
\setlength{\paperwidth}{33.1in} % A0 width: 46.8in
\setlength{\paperheight}{23.4in} % A0 height: 33.1in
\setlength{\sepwid}{0.02\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.20\paperwidth} % Width of one column
%-----------------------------------------------------------
\title{Title} % Poster title
\author{Blah Blah} % Author(s)
\institute{Department, University} % Institution(s)
\begin{document}
\begin{frame}[t]
\begin{columns}[t, totalwidth=\textwidth]
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\end{columns}
\end{frame}
\end{document}
Second part of your question:
This is only a quick and dirty solution, but if you adjust a bit the fontsizes and spaceings, you should be able to get the desired look
First you have to comment out the headline in beamerthemeconfposter.sty, e.g. the lines 192 to 211.
\documentclass[final]{beamer}
\usepackage[scale=0.78, size=a1]{beamerposter}
\usetheme{confposter}
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70}
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10}

\newlength{\sepwid}
\newlength{\onecolwid}
\setlength{\paperwidth}{33.1in} % A0 width: 46.8in
\setlength{\paperheight}{23.4in} % A0 height: 33.1in
\setlength{\sepwid}{0.02\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.20\paperwidth} % Width of one column
%-----------------------------------------------------------
\definecolor{headingcol}{rgb}{0.5,0.7,1} %Colour of main title
\definecolor{boxcol}{rgb}{0.7,0.2,0.2} %Edge-colour of box and top banner
\fboxsep=1cm
\usepackage{graphicx} % Required for including images
\usepackage{textpos}
\title{Title} % Poster title
\author{Blah Blah} % Author(s)
\institute{Department, University} % Institution(s)
\begin{document}
\begin{frame}[t]
\setlength{\unitlength}{1mm}

\put(-13,-50){
\begin{minipage}[t][0mm][c]{0mm}
\includegraphics[width=\paperwidth]{Black_Landscape.pdf}
\end{minipage}
}
\put(13,-50){
\begin{minipage}[t][0mm][l]{500mm}
\textcolor{headingcol}{\sffamily \fontsize{92}{48} \selectfont \textbf{\inserttitle}}\\[1.5cm]

\end{minipage}
}
\end{picture}
\vspace{13cm}
\begin{columns}[t, totalwidth=\textwidth]
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\begin{column}{\onecolwid}
\begin{alertblock}{test}
\end{alertblock}
\end{column}
\begin{column}{\sepwid}
\end{column}
\end{columns}
\end{frame}
\end{document}
This is my suggestion.
Leave the line
\documentclass[a0,landscape]{a0poster}
as it is and add the following lines
\usepackage{pgfpages}
\pgfpagesdeclarelayout{resize and center}
{
\def\pgfpageoptionborder{0pt}
}
{
\pgfpagesphysicalpageoptions
{%
logical pages=1,%
physical height=\pgfpageoptionheight,%
physical width=\pgfpageoptionwidth%
}
\pgfpageslogicalpageoptions{1}
{%
resized width=\pgfphysicalwidth,%
resized height=\pgfphysicalheight,%
border shrink=\pgfpageoptionborder,%
center=\pgfpoint{.5215\pgfphysicalwidth}{.47\pgfphysicalheight}%
}%
}
\pgfpagesuselayout{resize and center}[a2paper,landscape]
just after the line
\usepackage[svgnames]{xcolor}
In this way you will have the same document as before, but with a2 landscape size.
Output:
and these are the properties of the pdf file as shown by the viewer
that is to say a2 landscape.
Note that the new layout resize and center is obtained from the standard resize to with some adjusting to the center point, so to obtain the right positioning of the poster.

To get it in A1 format, replace the line
