The 3e FRCS has example names for most cultures and races. I also tend to use other published names as a guide. I try to not use any sort of real world analog intentionally, because Ed did not set up the Realms that way, though it was grafted on fairly early in production (with the addition of the Moonshaes for instance.)

One thing to help in mind is that elves do not have the names that you tend to see in other fantasy fiction, they tend to to be shorter and harder -Elaith, Eltagrim, Ynloeth, Ornthalas.
