Was the wiggle felt from the rear prior to the tires being rotated from the front? You could have a separated tire that could cause the wiggle and also the harder pull while they where on the front. I would ask for the printout to see what your specs are. If you have a camber or caster lead to one side it can cause a pull. I generally set camber even and have a .5 degree split in caster with the lead going to the left to comp for the road crown. Caster lead will be the smaller number and a camber lead would be to the larger number. Also I'd make sure you get a printout with before and after specs so you know where it was to start with.
