No problem, coolghoul. I definitely agree that "The God Crisis" might have fit better (but I can see why they didn't go with it).
If I might make a suggestion: skip Zero Hour. Infinite Crisis put the final nail in the coffin of undoing/wiping out all of the changes that resulted from ZH. That, and the fact that it was not a good story, by any stretch of the imagination. If you are a 90's sadist, that is someone who thought the excesses of the 90's is "fun" to read, then by all means, read it for the kitsch factor.
Some good things did come out of ZH, as I for one liked the "Post-Boot" Legion of Super-Heroes, one of the major changes wrought by Zero Hour. Oh and the events of ZH did cause Wally to run fast enough to enter the Speed Force, an event that changed him (but the scene is reprinted in Flash #94.
Perhaps the most lasting effect was the attack on the Justice Society, in which most of the original members were killed or aged. Really only Alan Scott, Jay Garrick, and Ted Grant escaped relatively unscathed (though Alan does give up being GL because of this, which is something that didn't last). With only one exception all of the characters killed from the JSA are still dead. This has an impact on the awesome James Robinson Starman series as the story begins with Ted Knight giving up being Starman due to what had happened with the JSA.
Of course, your mileage may vary, but again, I'd say that unless you are really curious and/or a fan of 90's comics, avoid it and just read the Wikipedia entry.
