Here's the use case that screws up a lot of people:
USE db_that_is_not_replicated;
INSERT INTO db_that_IS_replicate.tbl ...;
Surprise! That INSERT is not replicated. Workaround: *wild will notice it.
The other way around, the INSERT will be replicated, then hang replication because the
table won't be on the Slave.

I recommend to use the 'wild' modifier, if you have a default db and you specify the
schema in the query like update schemanotreplicated.mytable..... you will miss that.

Yes, doable. In my.cnf on master:
Binlog-do-database = dbname1
Binlog-do-database = dbname2
Would replicate those two dbs only.
There are many other combinations using binlog/replicate-do/ignore-db/table/wild. See the
manual on replication, and especially the flowchart on how those interact (sometimes in
unexpected ways).
