The boards I've got are about 2.5m long and 6" wide.
Put them on with as much overlap as will allow you to have them equally
spaced and cover the area required. Keeping them spaced equally is the
main problem and they look terrible if you mess that up.

How far should they overlap each other?
Enpough to cover the nails and a bit. The way you are supposed to put
them (thin edge up) means the weight is taken by the smallest section. I
always thought that is daft.

What sort of nails are best for fixing them?
Sheradised or galvanised or wooden dowels. Nail from the bottom up and
you will only expose the last set. Dowel from the bottom down or you
won't be a happy chappie after the first board goes on.

How far in from the edges should the nails go?
The idea is to stop the nail splitting the wood. 2" is plenty

Do I need to treat the boards with anything before I put them up.
You won't be able to paint the back or the covered parts after will you?
Doing it before you fix them is a sight easier. Then they just need
treating every few years. Creosoting means that you will never be able
to paint them or perhaps use any other treatment. Cuprinol or some such
is the best.

For future reference:
If you orer the boards from a timber mill you can specify what thickness
and width you want and get it treated too.
