First of all, this discussion is maybe irrelevant if you always create the grid "on the fly". Personally I usually create grids from a temporary table with the same name as the cursor I create in the application, and I do it visually in the form designer. This also mean that I usually move some fields, resize them, and so on.

1. Yes, persoanlly I have code like "Select * from myfile where .F. into cursor mydummy readwrite" in the form's load event, so that I have a cursor to bind the grid to.

2. As mentioned, I do that in the form designer. Some of my grids are very complex, with many calculated fields and so on.
