Hi Blaze, welcome to the message boards.

As Wing Chun is a Privateer you will want to make sure you train him in all the way in Will or Spirited as all his powers and strengths boost off of that. Training all the way in Rough will also boost his damage potential. Since he comes preloaded with Riposte training him in dodge will increase the chance an enemy will miss him so that Riposte can kick in.
Now that Blade Storm kicks in after a critical strike as well as after finishing off an enemy, it is always good to have blade storm trained. The rest is preferences. I like to train in Relentless as it is a joy to watch that kick in and see your companion letting loose with a string of hits that takes out your enemy or leaves them damaged enough that a pet can finish them off. Flanking is another useful one that you can use to plan around and guarente that extra hit from him if you place your companions right. With each thing you choose, take it up to level 2 and then go one by one with your increases, balancing them around until you run out of training spots.

I always wished we had a count down box so we could know how to space things out but we don't (Yet, hopefully) so it's best to keep things balanced out.

Since the last few are preferences, I am sure that your fellow Message Board Marauders may have some different styles that will work better or differently depending on what you want Wing to do for you.
