Being in the military and having packed many many seabags, I would suggest rolling, putting socks, etc.. in shoes, and packing toiletries in zip lock baggies. Also when you roll you will be surprised on the amount of room you will have left if you pack it real tight. I typically rolled up everything and stood it up long ways, not flat, that way if you squeezed the items between things it would just get tighter. Hope this helps.
