Most of what  you said the Democrats "need" to do was done in spades by Hillary.  Sadly  other aspects of the election overshadowed her policy proposals: 1) the e-mail fiasco which the GOP and the FBI director kept on the front burner;  2) her own gaffes like "the deplorables"...comparable to Romney's "takers" percentage; 3) her failure to engage the rank and file union members in PA, OH, MI, WI.  4) the perception of conflict of interest between her  Foundation and her role as Secretary of State; 5) Bill's gaffes: like meeting with the justice department while it was deciding wether to indict Hillary because of the e-mails.  In short,  the election was lost not because of lack of sound policy  While the election results might be disappointing to many of us we must remember that Hillary won the popular vote.  It was the electoral college (and a very small margin for Trump) that led to her defeat. She did not lose because of policy proposals, she lost because of poor campaigning.
