Answer
Ken,

I have a 2000 Maxima SE and all the things you have replaced and are going to replace have been changed on my car too.  It is just a matter of mean time between failure and the Japanese have it down to a science.  They plan all sorts of things to die after 100,000 miles.  Just change the idle air control valve and you should be fine for a while.  The coils on mine when first followed by the speed sensor and then the IAC.  So, yours is doing the same things.  After the IAC you should be fine for a while.  I now have 150,000 miles on mine...
