Now, when you have an elemental leak, that particular element put into the craft so far goes down. So if you have fire energy leaking, then all that work you put into raising the fire level starts to leak out, and the number goes down by about 1/second. To deal with leaks, you have to use the element weak to the leak's element; for example, if you have a fire leak, you want to feed ice fewell. It won't be a 100% chance of fixing the leak, so keep at it, and watch your impurity as you fix it.
Also don't be afraid to upset the balance of your synergy craft; as long as the ones that are required match up, you will succeed. For example, if you have a craft that requires 50 Earth and 50 Fire, having any amount of water won't affect the craft at all because it's not related to the craft at all. Having too much or too little of the required elements will cause you to fail, but not unrelated elements.
As for HQing, there's really no way to improve this aside from rumors that haven't really been proven. It seems to be pure chance, as I've HQ'd more than once on a recipe 10-15 levels above me. Maybe it's a case of T0 luck but it seems far too frequent for that. If you're curious and want to go with the superstitions however, they go as follows:
1) Match up fewell EXACTLY, the closer you are to perfect the better the HQ chance.
2) Don't let your furnace leak or threaten an explosion (i.e. don't let either pressure or impurities get too high), and your HQ chances will improve.
3) Thwack the furnace repeatedly when not at risk of an explosion until you get the message "the furnace has taken on a straighter silhouette." I can't disprove that this one might help because I've not determined an effect from the times I've succeeded at getting this.
These are the superstitions I've heard/tried when I first started out synergy with tatters augments on Sky gear, but I'm doubtful they actually do anything. I imagine it's just purely random.
