Could you pick me up at/from the station?

If the following sentences are both correct, do they mean the same thing?

1) Could you pick me up at/from the station?

2) Could you come and pick me up at/from the station?

If so, which would you use?

Also, don't you think that the verb "come" is redundant in sentence #2?

Finally, should I say "AT the station" or "FROM the station"?

Thank you.
