Can you help me understand Linux HA?

Pacemaker, Heartbeat, Corosync seem to be part of a whole HA stack, but how do they fit together?
How does wackamole differ from Pacemaker/Heartbeat/Corosync? I've seen opinions that wackamole is better than Heartbeat because it's peer-based. Is that valid?
The last release of wackamole was 2.5 years ago. Is it still being maintained or active?
What would you recommend for HA setup for web/application/database servers?
