I agree with Haisook on the FA, it is a highly recommended Power review material, but if nothing else goljan audios would help also, he links everything so well, I'd definitely recommend goljan audios, even though his book is overkill, but the least you should do is go through his audios, they'll set the base from the onset, general path things that he'll refer to in the systemic, so its really good for integration of material, esp when he stresses on the physio, biochem, genetics, pharm links as well!I think it's not about the books, nor the quantity of stuff you read. I know a lot of people who did only Kaplan + FA + Kaplan or UW Qbank and got 99. It's how you understand the concepts and integrate the information.
What I really, highly, wholeheartedly recommend is First Aid. And I can tell you with some certainty that Kaplan + FA for Pathology is enough; Goljan is not necessary.
One of the most often repeated advices of the top scorers has been keep your sources minimal and questions practice maximal, the sources you mention are time tested ones and have been successful. Revise it and see how you do on the question banks and you will get an idea of your knowledge.Do u think it's sufficient by watching Kaplan video lectures + Goljan audios + and additional question banks .
Do I need any additional books written by diff authors for step 1 preparation
