The Doyle/Halabi routing books you list are great and actually maybe too much just for the test, but knowing everything presented in these books will only make you better.  I used an older ACRC book as well and filled in the gaps with other material.  Besides, you will want the Doyle and Halabi books for CCIE preparation, so you won't go wrong buying them now.
 
I used the Cisco Press LAN Switching book, which I consider the switching Bible.  You can't do better for switching.
