Not saying you have too many resources, but better to know a few resources really well than use a bunch of resources and know them superficially. Use a detailed book like clinical micro made simple to learn concepts behind the bugs, and whatever you see in UWorld, feel free to write that into First Aid. I used picmonic (which only consists of microbiology from first aid) to learn all the first aid micro. I would first and foremost prioritize knowing all of FA Micro inside out, and then add with details from other resources. I scored 250+ and only used FA, UW, Pathoma, and a bit of clinical micro made simple to supplement it whereever necessary. That won't cover 100% of what you'll see for micro on step 1, but most of what you need to score well. It's better to know 95+% of First Aid's Micro section (combined with UWorld's micro) than it is to know 70% of the all the info in the books you mentioned.
