All your devices are listed under /dev but only if devfsd is running.
-t in mount is what filesystem you want the mount command to use. This is optional on some LINUX distributions.
The second part of mount your raw device usually /dev/hda, /dev/hdb, or /dev/hdc, etc and then following the partition number. For example /dev/hda1 for the primary or /dev/hda9 for the extended partitions.
The third part of mount is where you want to mount your raw device. It can be just about anywhere you have write access. Usually you mount drives in /mnt and then the directory. Don't forget to make a directory.
Sorry I don't know how to re-make my lilo when I'm using a rescue disk or Knoppix as my rescue disk.
All your devices will not be mounted until you told it to do so. LINUX can read NTFS and writing can also be done. Though its risky to write to NTFS in LINUX. If you want to mount your NTFS add -ro in the path. This will make the mount read only.
EXT3 is just EXT2 with jounalized file system, so you can still mount EXT3 as EXT2.
BTW, Look at http//www.justlinux.com . Its one of my top three links.
