90%+ of the materials out there are not going to make you a good analyst. While everyone needs a strong background in the nuts and bolts of the method, you are an analyst and not a programmer so the materials you study should be towards that end. For the analyst there is little out there but a few jems exist.
MacDonald, B. "Practical Stress Analysis with Finite Elements". This is a great primer on the subject. You should start simple and this book takes a basic approach to explaining many common principles analysts MUST know such as boundary conditions.
Cook, R. "finite element modeling for stress analysis". Another great book for the analyst, it will give you a much better understanding of the correct use for elements. What I like about this book is that it gives you enough theory to understand the elemnents and then explains the sources of error and common pitfalls. This is probably the best book out there on the subject specifically for the analyst.
Morris, A. "A Practical Guide to Reliable Finite Element Modeling". This book is about model validation, a key subject not often covered. Model validation is proving your model is representative of reality. Model validation should not be confused with model verification which is accounting for the errors introduced by mesh limitations (quad angles, etc. etc.).
AGARD LS 147. The lectures from Ian Taig in this series are invaluable. You should be able to find this document on the internet with ease.
There are other documents such as "Rules for Modeling" a collection of notes that was circulating on this website a while back that was credited to Ian Taig and Boeing, Bombardier, and Airbus references that you may be able to find if you are resourceful.
