While you're at it, have a shop deburr and "flex-hone" your seat tube to remove any corrosion that's already started in the seat tube. That way you don't mar your nice new post. Doing this and using anti-seize will keep corrosion at a minimum. But don't forget to pull the seatpost out occasionally to check for problems (annually or bi-annually). How often depends on conditions, mainly how much water your bike's exposed to.
