I think so ---but you can use eps and pdf files in the same document.  
First, chances are you have a command line program ps2eps, which  
converts your ps files to eps, calculating the right bounding box, so  
you don't have to do it manually; then

\documentclass{beamer}
%\usepackage{times}         % No need for this if you use mathptmx.
\usepackage[english]{babel}
\usepackage{mathptmx}       % But does this work with beamer?
\usepackage{helvet}
\usepackage{graphicx}       % I don't think color.sty is needed.
\usepackage{epstopdf}       % <- This converts your eps files;
                             % shell-escape is necessary.

To include pdf files in LaTeX you have to typeset with pdflatex,  
which you are obviously doing; and to include eps graphics in a  
pdflatex document you need the epstopdf package.

There is a beamer users mailing list:
