If it's supposed to remain on there, is the shim now useless or can i peel it entirely and use grease or some sort of anti-squeal?

You should have had a second shim that goes over the slotted shims. They come coated with a black rubber/plastic film and are placed between the pad and outer shim with a light coating of brake grease on both sides. They are supposed to be cleaned and re-used with new Toyota brake pads if in good condition. Unfortunately they are now technically ruined.
As you can see in the following picture in section 04945 you can see how the shims are intended to be placed on the pads.
If you are using Toyota brake pads (the good ones, not the cheaper ones, they come with their own shims), then you need to buy a new set of shims. If you are using non-Toyota brake pads you don't re-use the shims as most aftermarket pads come with their own shims.
