Short answer: Yes! :)
Might look at your weapon enchant too, I assume you've recently replaced the mace though given its source so for all I know you had it on your last one, tis up to you, get it now or wait til you have a better mace.
Gear wise you're sorted if you've not run heroics before then start off with an easy one to ease yourself into it. The biggest difference between normal and heroic I found when I first started them was that in heroic mode you're pretty much always casting, it can be quite a change.
Plus there's the hand and wrist enchants you might consider, again depends on when or if you want to do so now, but every little will help you.
Just doing some math: With the four extra enchants including your head slot you'll be an extra 181 +healing, for a total of 1529, that's more than enough to keep you going.
