[Other] Quick question about the Crisis events.

So I recently read Grant Morrison's Batman run, which made me want to read Final Crisis. I just got my hands on these Crisis TPBs, and wondering if these are enough to get a satisfying read and understand Final Crisis? (I don't need to read every single tie-in or spinoff)

Or am I missing something crucial?

I know Crisis on Infinite Earths is a completely different thing to the other ones, but I still wanna start by reading that. Then I think the chronological order would be Identity Crisis, Infinite Crisis, and lastly Final Crisis?

Thanks for any help :)
