infa-red lamps and under tank heating pads aren't good for dragons. It sounds like her temperatures coupled with her discomfort from shedding was playing a big part here (my guess is that they were climbing in certain spots to an uncomfortable level). The larger size of the crickets, and the fact that they were hiding in her viv could also contribute to the stress that added to her aggressions.
How are you measuring your temperatures? Base line temp should be taken (with a digital therm or temp gun) 3 hours after the lights come on in the morning. This gives the enclosure time to warm up, stabilize, and balance with the ambient temperature of the room, then maintain it's average temperature. Dragons don't have many sensory nerves on the underside of their bodies and under tank heaters have been known for shorting out and causing severe burns. If you would like to use it for some added heat at night, wrap it around the side of the enclosure where she can't lay on it. A dragons's health and digestion is directly affected by the heat it gets from above and stimulated by bright white light. They can see red lights at night which also disrupts their sleep pattern.
You might void the kale from the diet, and use foods from the chart at

One more thing..........her environment has changed radically from where you got her to your house. (thats a big jump up in most cases) and it sorta knocks them off a pretty level playing field. In the evening, just around sun down she will become more relaxed and much calmer like last night. It is a good time to hold and familiarize her with people. Then gradually move into her more waking hours.
Good luck and let us know how it's going.
