1 + 2:
Seems like you are looking for EXCHANGE PARTITION:
http://dev.mysql.com/doc/refman/5.6/en/partitioning-management-exchange.html

That way you can EXCHANGE a partition with an empty table and then drop the (now) empty partition, or exchange the table back as the original partition.

Yes if innodb-file-per-table is set, then each partition will have its own .ibd file (and can use DATA_DIRECTORY option). For archiving an innodb partition I recommend EXCHANGE PARTITION + DROP PARTITITION + FLUSH TABLES ... FOR EXPORT + ALTER TABLE DISCARD TABLESPACE.
See more about transportable tablespaces:
