Your running a similar set to I am though I've gotten a few tier pieces but I havn't gemmed it since I'll be have to regem once the new runeforge is in. Why would you gem for str/hit? Personally I would parry+stam and with the new threat change to rune strike, it's even more reason to stack parry where ever possible. Str for threat? Threat will get better once you have better gear and right now I have no threat issues. I can sometimes spike to 50k threat in about 3-4 seconds.
Personally just the runeforge will be enough and crafting the def weapon will just push you over the cap by alot. The runeforge alone will let you replace your gear with tier pieces and get rid of your def trinket without even gemming for def though it might be a few points depending on your gear. I have Death's Bite as my weapon and if I had to craft a weapon, it would be the parry one though I am very happy with my one atm.
