but where is "35 50" or "40 0"?
It's the coordinate in the picture - so "35 50" means 35th pixel from left and 50th pixel from head down - so on a picture with 70x100 pixels it would be the middle.
not all picture viewers support a feature to show the pixel location - but e.g. the gimp does - simple open the image, hold the mouse over the point you would like the road to end at and take a look at the status bar - the coordinates are printed there.
For the problem with the blender template: I do not know what happens there, but I know, that you should definitly use the template - without that template you will neither have the right lighting nor the right building orientation.
Perhaps you could ask Chuck, or AlexiaDeath in IRC chat. If bithunter32 or trimard is somewhere, you could ask these two as well.
Hope at least one of theme will read this post
