Well, that was two years ago. Nowadays...
I believe the recommended skills can be Tactics, Armor, Dual Wield, Concentration, Death Warrior Focus, Constitution, and Spell Resistance. I've learned that Malevolent Champion Focus gets diminishing returns, so I can't really recommend that skill any more.
Now you have three skills left to pick. As belarathmth mentioned, you can't pick Enhanced Perception without another skill.
You have a number of good skills for qualification, but I got well into Platinum without seeing strong healing potions. If you mod your build specifically for life leech per attack, this may help some. I believe that Riding and Alchemy are two very good skill choices. I used to think Evade was a good choice for the third Grim Resilience mod. I think Safeguard is the better choice and you get some mitigation. If you have armor with damage mitigation, I'd go with Toughness to enhance it further.
