Please Help me on LVM partitioning

Hi, I am new in LVM partitioning, I have a new supermicro with 2 hard disk (120GB) and I must install mail server on fedora core 3. So I need to use both hards to enlarge my /var and /home. Would you let me know how should I partition my hards.
At the moment I partitioned my first hard (with Disk Druid)
for /,/boot,/swap and /home and put /var on whole second hard and then I changed partition type of /home and /var to physical volume, but I don't know what else I should do to be able to enlarge these partitions with LVM and Volume Group.
I realy appreciate your help in this regard.
