It could be hard to get to the speeds you want without twinked gear, but then again, getting resists and DR are going to be difficult as well. As such, I would advise using 1 point BoS and dumping points into Fade, then use each one as the situation demands.
Get decent blocking. Trust me on this one.
If you are mostly untwinked, Black flail is a great weapon which can get you through almost all of the game (probably through the whole game with decent support.)
It may be an idea to hybrid with traps, because at the moment you have a mostly physical damage assassin teamed with a physical damage barbarian, Venom will kill Phys-immunes, but it will not be that powerful without many +skills. Traps afford you a measure of defensive safety as well as an effective 'fire and forget' second source of damage. In order to get the points, you might want to skimp on Shadow Master... I mean, afterall, you can just recast her...
