Here's a few notes in no particular order:
* I don't see the point in recommending an ER infuser bar or a Rt bar to a couple of beginners in Yak's. They don't have neither ER nor a Rt.
* If you did the Althea quests and came on foot via Ascalon Foothills then the areas after Yak's are perfectly in tone with the skill level you should be at around now. But if you came via the Nolani mission then yeah, it's gonna be a bit of a shock. And you're not gonna like the Frost Gate mission. :/
* As a rule of thumb, the number of Monk henchies in an outpost it's how many are needed for the area.
* Prophecies was designed to be played with exactly the henchies you see in the outposts (no heroes). You've already got an advantage since you're using two live players. So man it up.
* Alesia doesn't have touch healing skills. (I don't think any of the monk henchies in the entire game has any, though I may be wrong.) Her only touch skill is Restore Life, the res. She's running around because she's kiting. Which means the melee aren't doing a perfect job. Which is to be expected since they're AI too. Try calling targets, it helps.
* Bad hero bars will be even worse than henchies. The AI is the same.
* Don't underestimate GW just because you're WoW veterans (with apologies if you weren't doing that). Reconsider your party formations carefully and consider reading some of the beginner guides in the profession sections on the forum if you haven't already. You may also be interested in
this guide; not suggesting you reroll, but it might give you some fresh perspective.
* Since you're E and Me, take from Yak's the 2 melee, Alesia and your choice of Claude or Reyna. Normally you shouldn't need Dunham since you have a mesmer (plus he's very squishy, so's Claude). But I have this nagging suspicion that you didn't get any hex removal skills. You're gonna want one pretty soon (if not in Anvil Rock then in Kryta). BTW, the ele is also missing some cool skills if you haven't fully explored the quests and outposts before Yak's.
* Generally speaking, don't expect to do much with your second profession with the skills you've got. Or even later. Spreading attribute points too thin aside, a 13 ele and mesmer in Yak's have enough on their plate without trying to be a monk at the same time. You have your own specific skills if you want to provide party protection. It's true there are hybrid bars out there, but they're usually part of specialized teams, put together by experienced players, and/or designed for specific areas.
* Don't try to beat the game senseless, just go with the flow.

It's easy enough, no need to get heroes and whatnot. Learn to work together, to work with the henchies, don't jump over entire areas, there's no hurry. Do all the quests and let the game lead you, it's the most enjoyable way. Have fun.
