Thanks for the reply Khuon.
This bike shows very little signs of ever having been ridden. For now, I'll keep the suspension fork, but yes the seatpost has got to go. It has an adjustment on the front to lock out side to side play but that also reduces up and down motion as well and there seems to be no happy medium. I hope its a 27.2 seat tube cause I have several posts of that size I can replace it with.
