Berlitz does a good introduction to conversational French (and other languages) in a workbook with written explanations and activities as well as internet-based activities. It also comes with a CD so that you can hear the actual accent and pronunciation, which I really like. I used this book as a textbook when I was teaching a high school-level class for a homeschooling co-op. It's available at Borders and Barnes & Noble, as well as Amazon, for about $16.
