If I want to put a WordPress (3.2.1) site into Maintenance mode, is it still necessary to use a plugin? If so, is this a good option?

Yes there is. But it is primarily meant for short interruptions (such as during upgrades) and not very user-friendly. WP creates .maintenance
file in root (with timestamp info about time) to trigger it and removes after it is done.
See WordPress Maintenance Mode Without a Plugin for reference.
In practice using a plugin is usually more convenient and functional.
