Korra knows how to heal. She did it on Bolin's shoulder.

The Avatar doesn't need to know the sub skills because he/she is powerful enough by being able to bend all four of the elements already. Also, a fully realized Avatar can do incredible things that metalbenders or bloodbenders could never accomplish. I mean, Kyoshi created her own island, for example. So, a fully realized Avatar in a metal cage could just use the Avatar State to get out of it and doesn't need to know metalbending to do so.

Though, I still think the subskills would be useful for a pre-fully realized Avatar. Korra could have used some metalbending a couple of times. Bloodbending is a taboo subskill, so I doubt any well-meaning Avatar would attempt to learn it.
