1. select your object. Press "insert." Move the pivot point. Press "insert" again. Note that you should not move an entire object by moving all vertices at once. Rather go into object mode (right-click and select "select") and then move your object.

2. select your vertices. On the right side of your screen should be the channel box. Near the top you should see "CV's (click to show)." Click that. Now you should be able to insert a number in the boxes for each vertice. If you want to type in the same number for several boxes, simply shift-click each box, enter a number, then press enter.

3. Near the top of your screen should see three icons that look like red magnets. These are the snap buttons. By clicking a specific one, you can snap to the grid, points, or curves. (note that there are two additional snap button, but I don't know what they do)
