The skill mod that does work is the one before the slash in your skills sheet; the one you get from the profession and/or from being a Trandoshan. It's a one-for-one deal, if you have +250 unarmed damage, your VKs have +250 base damage. A 50-200 damage VK becomes a 300-450 damage VK.

The speed modifier is a percentage reduction. +30 speed means you reduce your speed by 30%. A VK with 2.0 speed in the hands of a TKA with +30 speed is actually 1.4 speed. That also means that at some point, your speed mod will get high enough to theoretically make your weapon faster than 1 hit/second even with the slowest special move, but since no attack is ever faster than once per second you are "capped". Also, once you hit +100 speed modifier (which all TKAs do at some point on the way to TKM) you will reduce your weapon speed by 100% which means speed is irrelevant.
