I find names impossible - in my head characters don't need any names
What I do is to just get on with writing the story down, using a random name for each character and place, as unless the name is key to understanding the story (which if you can't think of the name means it probably is not) then you can always go back and edit in the proper name once you discover it (search and replace in word is sooo useful)
Apart from that you could use a random name generator, but then you run the risk of having names that don't fit together in a country setting. I think a good start would be to think of the kind of societies that are present in the lands that you have made. Are they multinational, mononational -- that way you can start to use names with similar origines in the same nations.
Also remember that many names (especialy of places) are adaptations of descriptions of those places - either in current language or in older languages ( e..g. the town called Woodbridge - so call for its wooden bridge
