Hardware scan on boot, removal of hware and leftovers

On the second computer I had a 5 1/4 floppy and a ZIP drive installed when I installed v9.0; they were recognised correctly and entries written into fstab and correct icons placed on the Desktop. I have since removed both of these bits of hardware - but the icons are still on the Desktop and fstab still contains the entries for them. Question: is it only a matter of deleting the entries in fstab and deleting the icons on the Desktop to reflect the hdware I now have or is there a "gotcha", or two, that I need to know about if I did this?
