Importing Data with Single .ibd file
1) To get a single table restored and/or imported, use mysqldump. See the "how" links in my post here.

2) For a hot copy of InnoDB tables, use Perconas XtraBackup tool (BTW, the Percona website generally and their mysqlperformance blog are excellent MySQL resources).

You can also replicate from InnoDB masters to MyISAM slaves and the other way round (although why one would want to do this is a mystery to me).
