Naso Gems: Nazir, Birkat Kohanim, & the Nesiim

The gemara says a person can make his child a Nazir for chinuch purposes. Why would nezirut be included in chinuch - a person can go his whole lifetime without becoming a nazir!?!

What good is it to get a bracha from a kohen, if God wants to bless us He will, if he doesn't he won't??

Why does the Torah use the title Nasi for all the nesiim except for Nachshon ben Aminadav?
