Shimano shifter query

I have a fairly ancient Carrera Subway 2 and have recently replaced the chain, rear cassette and both front chain rings. The configuration of the bike is 16 speed, so 8 on rear 2 rings on front.

It has a three speed shifter on the front, so I was wondering whether it's common to use a three speed shifter when you've only got a two speed chainring? Also when I'm setting it all up should the derailleur only move across to number 2 on the shifter, or should I set it up so that I don't use position 2 at all on the shifter and moves from 1 straight to 3 ?

Hope this makes sense!

    Use shifter positions for small and middle rings. Set the outer limit screw to stop the shifter moving to big ring position.

    Thanks Les, when I've tried adjusting the front derailleur before there always seems a lot of resistance in the lever when shifting from the smaller chainring to the large one. I guess that by setting it up so that I'm moving from small to middle ring on the shifter will make it easier to change up.
