I don't know that block heaters are really a necessity here, but they sure are nice if you park outside.
As for how they work, I dunno. I just plugged my truck in. The current truck doesn't have it tho, but does have heated seats so I just fire it up, go back inside, get ready, leave and take it easy on the throttle until it starts to warm up (the needle starts moving).
