You can read and listen along manually to every lunar surface operation at http://www.hq.nasa.gov/alsj/frame.html. This is dozens of hours of audio (unfortunately in 12ish-minute segments). The transcript is annotated with helpful things, too - interviews with the astronauts in question to gain more understanding of what was happening, technical explanations and photos to explain what a particular device is, etc. There are a scattered few video clips as well for the most visually interesting moments.

The companion Apollo Flight Journal covers the rest of the missions - but doesn't contain audio, and is missing 13, 14, and 17 (but has 7-10, which of course aren't in the surface journal). It's still full of interesting annotations though.
