This is a good start. Thanks for taking the initiative!
I think you're over-emphasizing the fork-mounted cable hanger. That's a great solution (when possible) for fork shudder, but it only helps poor braking performance if the poor braking performance is caused by fork shudder. It might incidentally help other problems by forcing you to lower your straddle cable, but it seems better to address that directly.
It might be worth adding a section on Z-link wires, as there are several lengths available and choosing among them can help improve braking.
You could expand a lot on the discussion of V-brakes and mini-V brakes, in which case this thread should be renamed something more generic. A discussion of disc brakes is probably also worth having.
What you have about the trade-offs between mechanical advantage and pad travel is good, but I'd like to see it given more emphasis and perhaps expanded upon slightly.
