Richard did not know Locke, because he had not met him yet. But Richard can move in time (probably at will). After Locke tells him that he becomes his leader - Richard says, impossible, the selection process starts when the candidate is very young. I think that Richard then decided to visit Locke as a child. If you recall, he puts a bunch of items in front of the Locke as a child, and asks him which one is his. Richard wants him to pick the compass (which he gave him).
At the time, Richard had not *yet* gone back in time to see Locke as a child.
In the same way, Farraday does not remember telling Charlotte not to return to the island, because he hadn't done it yet. He will - remember seeing a present day Farraday in the Orchid when it was being constructed.
