The 556LW only handles the Passlock2. You will need a 451M door lock module for the (+) locks. The truck is pretty easy.
Here is a link to a Pictorial from a 1500 : https://www.the12volt.com/installbay/forum_posts.asp?tid=135786 Your 3500HD
should be very similar.

Can I use the 1701g for both the passlock and door lock

No, the 1701G works on the newer 2007 - 2013 body style trucks.
