I'm confused at how から works, and there's very little information on this
subject.

だから is used in front of a な adjective or noun.

い adjectives simply use 「から」.

Verbs can be in ます form, and only use 「から」.

Can 「ですから」 be used in place of 「だから」? And is the difference between:

「早く寝ましたから早く起きます。」 and 「早く寝たから早く起きます。」 different to each other the same way any
typical plain form - ます form pair of sentences is?

Does the same apply to 「猫が綺麗だから犬が怖くないです。」 and 「猫が綺麗ですから犬が怖くないです」?

question
grammar politeness particle-から
How does 「から」 work in regards to 「だから」 and 「ですから」?
> Can 「ですから」 be used in place of 「だから」?

Technically, yes. In practice, no. It's very rare to use ですます調（敬体）in this
situation. When a sentence contains the type of から (English "because") that
you are using here, it always comes with a second part. As long as the second
part is in 敬体 the whole sentence is assumed to be. So your example:

> 「早く寝ましたから早く起きます。」 and 「早く寝たから早く起きます。」 different to each other the same way
> any typical plain form - ます form pair of sentences is?

「早く寝たから早く起きます。」 is already considered "polite". That said, から here still feels
more informal than ので, so probably better is to use ので in business situations.

The situation you may hear ですから is when the second part is not present, either
because it is implied or because you are answering a question.

Sorry, I don't actually understand what you are trying to say in this example.
