No one ever regrets adding insulation unless it is so much that they no longer have space inside of their house.
on the super insulated house that i worked on we did both kinds of insulation outside, flat up to the walls if we had those walls and could easily get at them and running down and away from the house, the idea behind that type is to keep the frost away from the foundation walls so the foundation can take advantage of the 50 degree earth.
On NPR today they were talking about insulation like you want to do inside your basement and they suggested building your stud wall an inch or so away from the cement walls and spraying foam to create a monolith of foam around the wall and allowing you to add another inch of foam, if they were really flat walls you could get the same affect with an inch of foam board behind the studs.
