+1 on seeing a leather professional (whoops that sounds rather... um)
If your dead set on figuring it out yourself, you could also try visiting thrift stores and buying inexpensive leather belts and purses to try different techniques on, still the Brooks may be different. I'm wondering how a permanant marker like a sharpie would do for burnishing???
