Understanding the DC's Crisis events

Hallo all,

For ca. 2 years I am reading almost everything Batman/Batfamily from the modern age (almost 30 TPBs). I did branch out to Wonder Woman (read the first two Perez TPBs, ordered the last ones). Right now I am closing in on the Knightfall event. I have absolute no knowledge of The Lanterns (seen the movie), Aquaman, Hawkmen, Arrow (beside some of the TV Show) or Black Canary... I have the standard knowledge of Supes (didnt see the Snyder movie)

I started considering all those Crisis events...

Do I need to (Should I) read them all in order to understand them all up to Final Crisis?

Should I read Infinite Earths, if I only read modern material? Is it ground zero for modern continuity? Or is its place later in modern timeline?

Should I start with identity crisis?

What are your guys opinions? Sorry if topic is already on forums... I did make a search though...

You don't need to read the previous crises before Final Crisis. You can read that on your own.

You might as well avoid them. Well maybe read the Infinite Earths.
