First you need to determine what kind of enchanter you are going to have: Puller, Tank, Crowd Control, All of the above, or simply a bot that stand in your group doing these things for you.
My enchanter is a puller and tank, I do pet charming, soloing, and basically hold the attention of the mob while others kill it. For this type of play style I focus on AGI and AC. I can pull about 4 yellows in TBM zones and take the hits while I get them under control (mezzed). Often chanters tell me they don't charm because they are afraid of what the pet will do if it breaks... well then, be prepared to let the pet hit you while you recharm it or something. Duh.
Mana used to not be an issue, but there was a recent nerf that makes the mana return not give us quite so much.
Here is a youtube channel that will give you a lot of good ideas about playing an enchanter and what it can really do if you put a bit of work into it:

Clickies I think are a must: Unearthed belt, Gorilla Wrangler's Staff, Boots of the Mosquito, Curious Companion Compactor.
I will have to update my magelo and look at the augs but: Shimmering Black Pearl, Jonas Dagmire's Skeletal Parrot, Artisan's Prize, Sacred Prayer Shawl, etc. Those are lots of work, but it will build your AAs and abilities as you work on them.
TBM type 9 augs: I use mostly Vengeful with only one Sturdy. Type 5 augs are AGI (Swiftness).
