Ereshkigal, Some newbie questions. Options

Greetings all.

I'm new here (obviously), and am looking for some information regarding some things to do with the Necronomicon, and this is the only place I could find where people actually use it. Hope you don't mind.

A little background.
As far back as I can remember, I have been drawn to paths other than what the standard organized religions offer. I did much searching, tried some of the various ceremonial magicks, but never really caught on to it. More recently, I met a woman who is a priestess of Kali and has been doing a lot of work with me. It seems I am much more suited to being a priestess than a magickian.

This sort of path is much more rewarding tome than that of ceremonial magick, although she mixes the two somewhat. A few weeks ago, perusing one of my bookhaunts, I stumbled across the Necronomicon by Simon. I flipped through it a bit and it seemed well worth the meager price, so I bought it (it's the paperback version).

While reading through it I came across the Ancient One Ereshkigal. Something hit me, grabbed me like a giant hand. It seems I have a powerful attraction to this Goddess (and/or she does to me). I asked the Kali priestess about Her, and she told me that Ereshkigal is much like Kali, but didn't know enough to get in depth on it. I've searched the web for information, but there seems to be very little out there about Ereshkigal.

Do any of you have more information on this Goddess?
Does She have a sigil?
Are blood sacrifices acceptable? (We would offer some of our blood on Kali's altar at the beginning of rituals, and was told that blood of the priest/priestess was favored by Her far above that of animals. Would the same be true of Ereshkigal?)

I'm a complete neophyte to the Necronomicon system. I get soem mixed feeling about Ereshkigal from it. It seems that She would be one of the ones that would be invoked by using the Urilla text, yet no sigil or anything is given for Her. On the other hand Nergal, Her consort, is not in the Urilla text, but is given in other parts of the book. Does that mean Ereshkigal should be reached through Him? In other words does seeking Ereshkigal bring the curse of the Urilla text down on a person, while searching out Nergal does not?

Also I read posts by someone (smasher666 I believe) that mentions that using the Necronomicon in a priestly manner is different than from the point of view of a magickian. Are there any others who use the Necronomicon from a priestly direction? Can you give a bit more detail what the differences are for a priest/priestess versus a magickian?

Well, that's enough for now. Hope the questions aren't too stupid.

I figured that, better than starting a new thread, I thought I would ask here.

Has anybody found any ties between Ereshkigal and Hecate?

Looking through the greek magical papyri, I found a hymn that names Hekate Ereshkigal as if it was one goddess, and I'm curious about this since I find Hecate fascinating.

Either they were believed to be the same goddess, similar in attributes, or the old magicians liked to treat the gods like "legos" mixing them to see what came of it, lol.

Any info would be appreciated, posted here or PMed.
