Knitting Rules does have some stories in it but it also has a lot more stuff on actual knitting stuff - techniques, categories of projects (a whole chapter on scarves, a whole chapter on socks, etc.). It's also very good.
The order is close, but not quite. The actual order (with dates from Amazon) is:
"At Knit's End: Meditations for Women Who Knit Too Much" - Mar 15, 2005
"Yarn Harlot: The Secret Life of a Knitter" - Sep 1, 2005
"Knitting Rules!: The Yarn Harlot's Bag of Knitting Tricks - Mar 1, 2006
and finally "Cast Off" - which she is still writing and is scheduled for publication Mar 30, 2007.
I enjoyed all three. The first two are best catagorized as "knitting humor," while the third is a humerous book of tips and tricks. No clue on the contents of the forth - she hasn't hinted on her blog as far as I have seen.
