Well it depends on your build and stats. The bard way to go until you over gear the content is 1 hander + shield imo. I'm 36 now with 6.5k hp, 870 dps last time I checked and cant remember the other stats atm
If you struggle, go spend a mere 10k on the AH and get a decent 1-hander and shield
This is the build I am using atm.

I'll change a few things as I go up to 60, like ignore pain, heal rune on the charge, the resist shout & the stun, but some of those are there to stay.
With this build if you Leap into the mobs you start with that +300% armor. It helps allot
Then a rend to help with healing & dmg
Frenzy for to get stacks up
Revenge if it procs, and specially if u need healing
If its elites you have WotB
Charge to get out or dodge or to the annoying range dude. In inferno it will be insanely cool with the healing rune.
Continue using the leap for the armor buff and keep rend up and all is good.
I find it really easy and quick and loads of fun. What can be more fun than jumping and charging all over the place and then turn into a Super Saiyan
Regarding Intel. It is not something you look to get on your items. If its there with the other stats, then cool its a bonus, but it gives far less than other things do. By far your best defensive stat is Resist to All (10:1 vs armor) and 2ndly Armor (and there are breaking points for armor also)
@panthis, DH's are so op with regards to dmg. Mine facerolls also.
