Hi Libby

I too have recently discovered Yoga Nidra which focuses mainly on mindfulness and have also found it to be a great help,there are free sessions on Blooming Lotus yoga website if you are interested in anymore of those.
As for the Buddhism i found that the best reads have been The Miracle of Mindfulness by Thich Nhat Hanh,It is more a manual on meditation but has lots of suggestions and methods for becoming more enlightened,Also A Path With Heart -by Jack Kornfield is along the same lines.Deeper reads are The Foundations of Buddhism – Rupert Gethin and The New Heart of Wisdom-Geshe Kelsang Gyatso. Hope these suggestions help a bit.
