Working with partition tables can be destructive. Whatever you do, make a backup of all data first.
You may want to check into LVM, which comes free with Linux and is standard. The basic idea is that you can add LVM controlled disks and partitions to an existing LVM partition and thereby increase its size. The constructed partitions will appear as one volume from the OS level. You can also convert non LVM disks to LVM without loosing the data.
There is plenty of documentation and tutorials available when you search with Google using e.g. "redhat linux lvm tutorial" and "linux lvm convert disk".
