This following is my opinion and suits my playstyle

I have my Claws / Ulak, Martial Staff, and Bladestaff skills maxed as they are your primary damage dealing weapons. Of course you can substitute any of the HTH weapons as you see fit. If you use 1 claw and 1 handwrap you may run in to problems not having enough points.

Martial Sword is IMO more of a defensive weapon and I perosnally don't feel the need to put points into it. Same with Shurikens are just for pulling. So I dont bother putting points into this as well.  (If you play on a PVP server you may want to reconsider this though as ranged damage is key as most classes will try and kite you.)

Also keep in mind that even if you arent putting points into a specialization don't neglect the general skill it's based on as who knows what "phat lewt" could drop and leveling up your weapon skill from a 0 would be the suck.

Hope this helps,

Hand to Hand weapons (Claw / Ulak / Handwraps / Knucles will carry + 5% / 2.5% to crit main hand /  offhand.
Martial Swords will give a bonus to parry
Martial Staff / Bladestaff will grant double damage on a crit.

My personal play style has me using Claws for the + to crit then macroing weapon changes so I use the blade staff / martial staff during special move chains.  After the chain is over I switch back to claws.
