I agree, the only Step you should be concerned with at Step 4 is Step 4 and you absolutely need a sponsor to talk through step 8 and 9 so that your alcoholic mind does not use it as a loophole.
I know for me that I can have the urge to apoligise and make amends for absolutely everything to relieve my guilty conscience and I will keep doing so, on and on until I feel better, regardless of how crap I make other people feel. A sponsor helps me see when I am making amends for my sake or the person wronged sake.
Once you work all the steps you will know if you are making amends correctly....all will become clear.
In the meantime, just think Step 4
