I must agree with Jeremy, with one small caveat. Absolutely do not
attempt this with the MySQL 3.23.x branch. When replication breaks (in
my 6 server setup it breaks about once a month on one server, so not bad
at all), the ability to execute "load data from master; start slave;" is
very, very worth while.
Overall though the architecture you're suggesting, and Jeremy and I have
both setup, is absolutely the best for a setup like yours.
Hope that helps,
Nick Harring
