I also saw the article on using spray and bat insulation together. Looked very promising, but did not read it in detail. One thing that stuck out though was that the thickness of the spray foam was important to control condensation from occuring in the bat insulation. And of course that depends on your local weather conditions.
The other thing about spray foam and diy. I checked the internet costs to do the spray foam myself and also had the local contractor bid the job. Turned out the local contractor charged something like 3 cents more per square foot, but installed 3 times the thickness the diy foam would do. So be sure you give the local contractor the chance to at least bid the job before you commit to diy.
