Yes, you can use Heartbeat to trigger failover to the slave when using
replication. There's a number of articles on the topic. Google 'mysql
replication heartbeat'. BTW...you can certainly use two dissimilar
systems for a MySQL/DRBD/Heartbeat cluster, but you won't have the same
performance as if the systems were identical. For home use this may not
be an issue. Just depends on your use case.

Can MySQL replication be used together with heartbeat?  Any good tutorials on this topic?

Thanks

If you need only mysql clustered, i would advise you to use mysql replication.

Assuming I want to use DRBD with MySQL (together with heartbeat) in a
two server configuration, do both servers have to be exactly the same?

I'm thinking of setting up a home system with one powerful server
(active) and a lesser server (passive) to be used only upon emergencies.
I know this is far from ideal, but its cheaper and wanted to know if it
can be done or if it would be a pain to setup (I'm not a huge techie so
don't want to deal with too many setup complications)

Thanks,
