Lobbying and pacs weren't created by citizens united.
Honestly, reversing citizens united is the only part that's needed. Pacs and lobbying aren't intrinsically bad, they just need regulation and oversight that they don't have because of citizens united.
A group of people showing able to pool their resources to advocate for legislation, and people should be able to ask their representatives to take action on their behalf.
Pacs and lobbying are now far more than those two things, so we need regulation, but we still need them.
Citizen's United is what is preventing the government from abolishing lobbying, so abolishing lobbying implies reverting Citizen's United. You could either have one or the other on the list, but you don't really need both.
