James Filici’s ’The Complete Manual of Typography’ is an excellent technical manual for setting type properly, and your on the right track w/ Bringhurst.

One good technique for learning type usage and combination is documenting what is around you. Take pictures of things that work. thats what it is all about; what works. Photograph a magazine layout that is striking, or a book that reads easily, or signage that clearly communicates. When the time comes for you to solve a type problem you will have a reference library. It is good to have work not to copy but to emulate. Observe what the artist did in terms of combination of type styles, proportion, spacing.

It is good to know what the masters think about type usage and combinations. It is also important, in my opinion, to see what others are doing; type in action. What does/doesn’t work.

I would recommend these two books:

Jost Hochuli: Detail in typography
