Sorry if I don't have the correct terminology, I am still somewhat a linux novice.

I have a computer with four hard drives (sda, sdb, sdc & sdd) in it. I am going to add a fifth (sde) which will replace two others (sdb & sdc).

Adding the drive and moving data to it is the easy part for me. What happens when I physically remove the other two disks? Will the labels move down? Will I need to manually edit fstab and fix the problem?

Letters are assigned on the basis of which drive gets enumerated first. The first drive gets /dev/sda, the second /dev/sdb, etc. If you want to avoid having to modify /etc/fstab then you should consider using the filesystem labels or UUIDs instead of the device node.
