[CentOS] installing centos with oos ntfs format drives

greetings.

i am going to run a fresh install of centos 6.4 and want to mount 3
partitions of oos that are formatted as ntfs in an oem installed box.

if during install, i set up partitions /dev/sda1, /dev/sda2, and
/dev/sdb1 as ntfs, will install install ntfs software or will i have
to select it later on in installation?

also, is it better to mount them under /mnt to keep /media clean?


tia.
