Need help with Impact Fix

[Bendet2]

First post here so bear with me, Could somebody explain an easy step by step routine that I could go through when addressing the ball, with every club to take a proper impact fix set up. I know to get my right forearm on plane with my clubshaft (ususally do this by holding the forearm and clubcshaft out in front of me, perpendicular to the ground) but I am unsure as to how far forward to "press" my hands (probably the wrong term to use), is it just until the left wrist is flat? If I am to mimic impact at startup, should my shoulders be slightly open? Do I change the takeaway at all? Lots of questions.
