Page Break lines indicate where will the page end if you will print your 
diagram. You can change settings in Page Setup.

Grid is just something to help you create objects with some exact 
length. In Dia the grid is resized when you zoom in so you can still use 
grids on smaller distances.

It's not possible to align elements relative to pages in Dia. If you 
really want to you can make a group of elements to be aligned, place 
another element in 0:0 and then select the element and the group and 
align to left and to top... But you'll probably just want to select 
everything and move it.

Or you can use Page Setup and select "Fit to", but it will not move your 
elements it will move page breaks (meaning your diagram, when printed, 
should start from upper left corner of the page).
