girl, you're strong as a beast you surpass me on my weights/reps, and Im sitting here reading this... all ashamed ... 

 joking, overall really good progress, especially the passion, the drive, the vibe here, its all so vibrant, I can almost feel the energy and see you smile just by reading it all... 

 very good, it should turn on alot more people do more reach for more just by reading what you post here, very well!
 I have noticed one thing when travelling and trying different gyms, machines would be similar per exercise but different by manufacturer and weights dont match one another, in one gym 50 is too heavy on this one machine, in another its just way too light, depending on the pulley/gears size/ratios and setup it could give world of difference, lesser/greater load on the same numbers, so that's that, but on the screen you beat me to the ground, well done 

 really good.
You ask about changing things around, how about keep and try to stick with your routine but try higher intensity? Im talking about - do your warmup set or two but not with the working weight, something around 50-60% of you working weight, and then do the one and final working set per that exercise, ~3 seconds per each controlled movement, etc dumbbell curls: raise 3sec - hold/squeeze 3sec - lower 3sec, via full range of motion and see how does it feel? 
As you mentioned you have extra power where you feel like you could go more do more, this should tax your energy levels very well 
 
I can imagine exercises can get real boring and you'd want to try something  new, but think of it this way - its easier to get bored than to discover  something exciting, just an idea to think about...
