I am starting my PhD in Child Psychology this August and currently collecting all useful resources that might be helpful with my journey ahead. I don't know if anyone has tried out Zotero. I feel it seems more useful for people who just started a project. What do you think?
Could anyone recommend useful qualitative data analysis tools? Any tips or recommendations on how to organize related resources and data for a PhD starter would be most appreciated!

You could try a Content Management App like DevonThink Pro (or the PC equivalent).

forget to link the website www.zotero.org apparently it is only used with firefox. I think it is very good that you haven't downloaded many resources but instill in the process of searching for articles. This tool can very useful. Do share what is the most useful tool for you to organize your literature
