No. You need RAID >= 1 and proper backup procedures for that.

No. You can have /, /home, /tmp and swap _either_ as logical 
partitions in the extended partition _or_ as logical volumes in 
the LVM but not both at the same time.

Extending partitions or logical volumes is always easier than 
shrinking them. Shrinking a LVM root volume is especially 
painful, see:
