Hey Firefly, I'm quite happy to offer info on my experiences over the years.
The Intelligent Investor is an excellent book and one that my father introduced me to years ago. Once you are familiar with its content I would suggest getting the classic 1934 edition of "Security Analysis" by Graham/Dodd. It is not for beginners and you should take the approach of studying it and taking notes, rather than just reading it. I don't think it is still in print but I have found bookfinder.com very good for finding somewhat rare books. There are probably endless amounts of other books on value investing, but I think if you get to the point of understanding the above 2 you won't really need any others, it could just end up being confusing and possibly even wrong information. What I have found beneficial over the years is to simply pick up one of the books and re-read a couple of chapters, which reminds me that I haven't done this in a while. You are better off spending more time reading annual and quarterly reports than reading possibly too much about value investing.
Applying these techniques to funds and ETFs can be very tricky and time consuming as you would need to analyse the underlying companies individually. That doesn't mean that ETFs are not a good way to invest, their obvious benefit is the fees and purchase costs, and quite importantly the diversification they offer if you have a limited starting capital. Personally I mainly invest directly in equities after applying some basic value investing techniques. If I am not mistaken, it is mentioned in one of the books that tracker funds are useful to those that are not willing or able to put in the time and effort necessary to perform the research and analysis.
Best thing you can do is read the two books and then start analyising and keeping track of your findings in a spreadsheet.
