Upgrading a weapon will give the most benefit, but I would also suggest upgrading the relic of Xuen. That's BiS pre heroic mode, so will be quite competitive even into T15. If you manage to get a Sha-touched weapon prior to 5.2's release, then definitely upgrade that too.
As for Ask Mr Robot? Apparently if you use the Windwalker stat weights, it works well. But I'm not speaking from personal experience here.
