Yep. Can't have more than 15 partitions on "SCSI". With
IDE, you can use up to 63 partitions.

Certainly.

Yep. You'd need to remove one of the existing partitions, though.
You'd then use this partition number to be your "Physical Volume" (PV)
which will be used to create a "Volume Group" (VG) and in this
VG you'll create as many Logical Volumes (LV, partition, if you
like) as needed. The partition would span the whole available space.

I only know of one LVM howto and that's an excellent one.
See <http://www.tldp.org/HOWTO/LVM-HOWTO/>.
