I highly recommend Nakamoto's books at the end of the list. there are 2 very good books i used as an undergrad and we had those in a few of the labs I worked in...I will try and find the titles...The BIG BLUE SPECTROSCOPY BOOK...It is an Eduational and Industry Standard.
This Aldrich Link: These are great...

http://www.dmoz.org/Science/Chemistry/Analytical/Infrared_Spectroscopy/Nickel and cobalt complexes have been studied extensively using DFT. Their geometries are of interest due to their applications as catalysts. There is XRD data to support the structure/gemetry of many species. And XRD data cannot be disputed...Usually with spectroscopic methods you have to do more than one type of analysis ...as you have indicated...to get a complete picture of your species of interest. But it is a good way to become aquainted with all the methods and understanding how to interpret spectra.
