Mastering Yang Style Taijiquan by Fu Zhongwen
Good, detailed information on Yang style and its 103-form in particular. Has sections on push hands and classics, but not much about fighting applications or weapons. I find it hard to imagine a better text for beginning to intermediate students of Yang Taiji.

Wing Tsun Kuen by Leung Ting
I can't really comment, but this seems like a solid technical training manual for WT beginners.
