if you want active/passive type cluster (HA, not load-balanced), use 
'heartbeat' and 'stonith' and use apache on the machines.

if you can make do with non-realtime replication of your web files, use rsync. 
if you need realtime replication, look into the kernel module drbd. use 
module-assistant to help you compile/install it if compiling kernels is not 
your thing. drbd is a 'RAID over TCP/IP' and has been working quite well for 
me.

for a web server, use apache of course. configure it identically on both 
machines. etc..
