Apple has a document, or rather many, that you can find out about at
http://developer.apple.com/hardware/ve/quickstart.html
I found their documents to be good references, although if your algorithms
are pretty common, the vDSP framework might already have implementations.
I've only ever used the C API directly, and had no trouble converting a
Mandelbrot calculation to Altivec. It gave me a 100% speed increase, when
combined with some loop unrolling. This was without compiler
optimizations.
