Heya, it took me a while to get my head around referencing when I was at uni, so I feel you! The way I normally wrote my essays was the other way round to how you've described it above - I'd (skim) read texts and summarise the main points in my notes then if those supported my argument, I would then cite them in my essay. It depends on the requirements for the essay/ report - if in doubt I'm sure your tutor would be very happy to clarify - about how much of your own opinion you should build in. My holy grail for referencing was Cite Them Right - your uni should have a subscription to this and it explains exactly when and how to reference. Good luck with the report!
