These three /dev/mapper volumes are your filesystems. I am in a system 
currently that does not use have an LVM except for a swap partition from 
the other installation that uses LVM for the swap and / partitions.

To mount the partition, you put the /dev/VolGroup00/LogVol information 
followed by the location to mount the device as below for my swap partition.

/dev/hda5vol/LogVol01   swap               swap    defaults        0 0

Sorry so brief an expalanation. This information should be in 
/etc/fstab. Usually the first entry is by label and then followed by 
mountpoint, followed by filesystem and so on.
