If I'm following you correctly, the spring is being pulled on by an external force causing a reaction force in the spring. If you're looking for the work done by the spring force, you do not need to account for the external force.
And remember that work is a vector, so what your sign.
Ah yeah, that's exactly what I was trying to figure out. And I got a negative sign as my x values are positive; I'm guessing that's the resistance in the spring, whereas inverting the sign is the work done by the hand that's pulling the spring? I'm probably phrasing this wrong.
I'm just trying to understand this problem completely since I'm doing a screencast of it as homework and he grades understanding as much as getting the right answer.
And thanks a ton guys, my physics teacher's a genius but doesn't teach all that well >__>
