There's a differenc of nuance. 'things good to know' may include things that are not good, but are usefulto know.

Hm. I don't know if there is any difference between necessary things to know and things necessary to know, but I wouldn't use either of those sentences. Instead, I would say:

• I know all the things I need to know.

Or, perhaps:

• I know all the things it is necessary for me to know.

I have the same doubt about the order of the word `necessary´ in the sentence.
Which is correct? or are both correct? in
a. The documents necessary to travel, or
b. The necessary documents to travel.

Which is the grammar rule to use a different order in the sentence of the word `necessary´in case that both options are correct? is there any difference in meaning?
Thank you.
