Heartbeat will do just about anything. We have filesystem failover, Luster, Apache, MySQL, and a custom application that I wrote all failing over on one node. I have another that is a ISP gateway and another that is a firewall/gateway. Heartbeat comes with some handy scripts to do IP failover, and filesystem (actually mounting disks on a SAN or iSCSI, etc). You can also run init.d scripts in the heartbeat conf. You specify what order you want the services to come up and it will take them down in that order.
If you want to do NFS, you use the same config on both machines for NFS, prevent NFS from auto starting in rc.*, do a noauto in /etc/fstab for the shared disk, and then configure in heartbeat a shared IP address, run the heartbeat mount script and then run the NFS init.d script. For the easy cluster you specify all the services on the first node and just the name on the second node. I find Linux heartbeat much easier then Windows Clustering. If you don't have shared storage you can use DRBD to create fake shared storage. Never used it though.
