Active Directory user import fields

I'm trying to go through the schema that was published back on Feb., 2006 and also looking through the database.

I see entire user's names crammed into the First Name field.

Is this due to the Active Directory import? Do you map an entire Users container into one field?

Is it possible to be able to map a First name into a First name field? Last Name into a Last Name field? And then reference it somehow in the notifications when using "$RequesterName" ?

We're just getting killed with getting approval (from the boss) for more licenses and being able to roll this out completely without these notifications fixed.
