"There was little white worm/larvae in little groups between frames. Also there was this brown slimy goo... looked like runny brown kitten poop??? All over the bottom. It also smelled rotten, almost like a roadkill?"
Well it sounds to me that you have had your first SHB slime job. Really sorry to hear that.
"This happened all of a sudden, I was just in there a week ago and all was well."
Yep, it doesn't take very long.
"Also seemed a bunch of hive beetles too? Also all of a sudden I seem to have a bunch of hive beetle in rest of my hives."
They have either hatched or found your hives in numbers.
"I have placed traps."
The only effective trap system I have found is full bottom traps. I have heard that others have had success with other systems.
"I did not take pics, actually I burnt it up,"
The equipment can be salvaged, no need to burn. I just freeze for a couple of days then put it on a strong hive. If it's not to bad that is. If really bad I hose it off first.
