Answer 1

Firstly, read the MySQL Replication documentation. It's very useful and will answer a lot of questions you haven't even realized you will need to ask.

Handling replication in your application means you can distribute the SELECT statements. They don't need to replicate and will return the same results no matter which server they hit. However, UPDATE, INSERT and DELETE statements must occur on the master.

Remember that replication spreads the read load, but every server still has the same write load. Depending on your query read/write ratio, this might not be appropriate. (Check out LiveJournal's presentation about how they scaled. It's easy to find.)

Edit: Meant to reference LiveJournal, not Facebook. D'oh!
