Honestly UFAP (Uworld, First Aid, Pathoma) is all you need for Step 1 to do well. It is totally sufficient by itself. These should be your core resources. However, Sketchy Micro is a nice addition, it definitely did help me out on test day recalling obscure details. I wouldn't bother with Sketchy Pharm, the Pharm in First Aid is enough. Goljian audio files are good to listen to while commuting or working out if you want, but not necessary. Anything more than the above and you are going to resource overloaded.
Here's what I would do if I were you: I would get some of the annoying "pre-work" out of the way to make your dedicated course smoother. Start watching Pathoma lectures and writing notes into your Pathoma book. He says lots of valuable info that is not written in the text. This way, during dedicated you can just re-watch the lectures as a refresher and study the notes you already have. Similarly, with Sketchy Micro I printed the photos and made a binder with them that I annotated because while the online versions are best for quickly testing yourself, I did find it helpful to take my own notes (they also sometimes say things or elaborate on details that are not written down). So you may or may not want to do that, but I would go ahead and make your first pass on watching the videos at least. Again, during dedicated you can cruise your way through the videos on your second pass then just study off the images. This will save you time and stress being already familiar with these resources. Also I would start using First Aid along with your organ system blocks but I wouldn't stress it too much. A quick read through of the relevant organ system for the block you're on can be a great review the week of your exams.
You can chug through this stuff at a gradual pace on the side, definitely keep classes your top priority between now and dedicated.
Save UWorld for dedicated. Try to get through 2x.
I wouldn't bother with the other Qbanks but that's just me
