Yea, like Perky said those are all good skills.
Double Attack is great cos it can't miss, and Riposte does high damage. But if you want to kill them
really fast you'll want to wear Shadowstrike, Double Attack, or Quick Strike rings. Those skills give you fast instant damage instead of DoT- so your fights will end quicker. (Sucking a bunch of mobs onto you at one time is when you'd want to use Riposte, but you'll be real squishy due to he farming build that follows, which is why I don't recommend doing that haha)
For simply Farming I'd use a Dagger for fast attack speed and then Axe offhand. I'm sure you can scrounge up some bone shards for Beastbone armour to equip your Rogue with.
Stats should be Average Str, High Dex, and Average Health. The reason dex should be high is that Shadowstrike and QS are Dex based skills and will deal higher damage the higher your stat is. Riposte may or may not be (forget).
You should be level 155-160 to kill most of the Boggans without too much of a challenge, and they'll still have high aggro on you at that point.
That's what I did at least

Good luck farming!
