2. Here’s a PDF about using grids when creating page layouts.
here’s a quote from the PDF
Why Use a Grid?
That’s a fair question and I get where you’re coming
from. Grids give you an opportunity to design in the
fast lane, they make your design semi-autonomous,
which may turn a lot of you off (keep an open mind
or you’ll miss out). Essentially they give you a tool to
create with an underlying consistency and allow you
to think less about basic design principles and more
about finding a design solution. This allows you to
design at a more advanced level, being more able to
think about advanced concepts like page rhythm. They
also give you a structure place your page elements on.
3. Here’s a very basic video introduction to working with grids in InDesign
