Excellent again! Are you getting 2 guys and 1 truck or 3 guys and 1 truck? Reason I ask is because that will speak as to how much stuff is to be moved. Since I worked for this company for 2 years when I was at UVA, I know a lot about them. Here is how the moving drill should work and my advice. First of all, have plenty of disposable cups, ice and water ready for them at all times - movers are thirsty. Secondly, these guys generally work VERY quickly and that is for a good reason. They want a good tip. Generally, I would tip each mover at a minimum $20 for a smallish load or $40-50 for an all day ordeal. They will load the truck in a very specific order with large weight bearing furniture such as chests of drawers, end tables, etc. Then they will stack boxes on top of those and finally put smeg like chairs wrapped in moving blankets on top. The first few rows loaded on the truck will be like this. Once that is loaded, they will then bring in the matresses and "wall off" that section of the truck. They will then load the last odd items, tied off to the walls of the truck - things like china cabinets, for example. Lastly, they will load upholstered furniture like couches and chairs and stack remaining smeg on them.
Once they get the truck loaded, your Mom should plan to follow or beat them over to the new house. Once they get the truck into position and the ramp down, furniture starts flying off. Your Mom should be standing in whatever room they are going to enter the house from and direct each piece into the position that she wants it in to a particular room.
