Hittite questions from "Illustrated Dictionary of Mythology"

It's a book for youth and up, but the Hittite myths section is quite
interesting.

There is a mistake made in assuming that Teshub was necessarily the
Hittite name for the thunder-god - this would be the Hurrian version,
while an Anatolian Tarhun(t) is known from at least Luwian.

However, that aside, the explanations are very interesting:

"Waving his thunderbolt, he (Teshub) rode across the sky on a
bellowing bull"
Is this an attribute of the Hittite Storm-god or the Hurrian one?

"TELEPINUS: Teshub's son, Telepinus, the god of agriculture, went
into hiding and the crops began to fail. When found, he flew home on
an eagle, and the crops began to grow again."
My question: Is Telepinus' name possibly IE in origin?

"HANNAHANNAS: The mother goddess Hannahannas was important in finding
Telepinus. She suggested sending a bee to look for him. The other
gods ridiculed the suggestion, but the bee found Telepinus, sleeping,
and stung him awake."
The name is a reduplication of Hittite "hannas", Grandmother, so mybe
it means Great-great-Grandmother, or Ancestral Grandmother. It is
possible this is a Hittitization of a pre-Hittite goddess;
alternately, this might be a reflex of something the Hittites brought
with them (whether they picked it up en route to their current
location is another question).

"KAMRUSEPAS: The goddess of healing and magic, Kamrusepas was called
on by the other gods to heal Telepinus after he was stung by
Hannahannas' bee. Only after Telepinus was restored to health could
he return home."
Despite the Hittite "-as" ending, I can't say this name looks exactly
Indo-European in origin. Could it be?
(On another note, the picture of her in the book looks quite
attractive and young! ^.^)
