Johns' Flash and JSA, which are available in omnibus form were solid runs on interesting characters that planted a lot of seeds for all of the events that you mentioned.
I would recommend reading the trade of Identity Crisis and all of the material collected in the Infinite Crisis Omnibus. They are available in separate paperbacks.
In between Infinite and Final Crisis, you should get the 52 Omnibus or the new edition chunky trades. It is by Morrison, Johns, Waid, and Rucka and covers a year chronologically in real time for the DCU.
