Jon-Kabat Zinn's work got me into meditation, so I wholeheartedly recommend some of his programs. There is a strong scientific backbone behind what he does.
There are all kinds of different meditations, but I believe vipassana meditation is the most extensively studied, and also the most simple/beneficial to do. One book that really bridged the gap for me on meditation was Mindfulness in Plain English. It lays out what meditation is/isn't and offers a straightforward way to do it. It's free to read online here: www.urbandharma.org/udharma4/mpe.html
but it is also worth buying because of how precise it is: /www.amazon.com/Mindfulness-English-Bhante-Henepola-Gunaratana/dp/0861719069
If you want to go a little further, I would also recommend Bill Harris's Holosync program. His program uses brainwave technology to induce deep meditative states. I found even more benefit doing those, and it's rather easy to do (just listen to a meditation track 30 min - 1 hr every day). The program offers a money back guarantee if you aren't happy with it for any reason.
