Don't bother to mess with your axles or CV's they are just fine as they are, you are more likely to snap the short inner axle than anything and there is not upgrade for it. Plus if you do ever break one it is much easier to get a replacement at the local parts shop. My brother did the aftermarket stuff and broke more of them than the stock stuff. Yeah I've had to replace stock CV's but I never broke one. As to the upper arms same deal broke aftermarket arms but never an Oem. I'd just get a ball joint spacer and be done with it.
