What do I need to do to get Matriarch Aethyta to show up on the Presidium? I do not see her there in my playthrough, and I don't know if that's because I haven't done something I need to, or I'm looking in the wrong area, or what.
I know you can see her, because of this question.
Sorry to be the one to tell you, but there is no good ending. Even the "best" ending is still awful.
You need 4,000 or 5,000 effective military strength to unlock the "best" ending. The difference depends on a choice that I won't spoil for you.
The "Premium Collectible Pack" comes with the purchase of action figure packs, as shown here.
The linked page describes the bonus in the following text:
These products contain a code that can be redeemed for bonus content for Mass Effect 3 multi-player . The pack could include character boosters, weapons, weapon modifications and upgrades to make your multi-player squad stronger.
This translates to the "special bonus for dedicated Mass Effect fans" you referred to in your question. It is misleading to have the word "free" included in any sort of description of this pack as you're required to spend a substantial amount to get the figures and code.

She was at the bar by where Liara sits from the beginning of the first time you can go to the Presidium.
I do not have anything official at the moment, but after the attack on the Citadel, a lot of NPCs change around. It is possible that, she is one of these NPCs as I did have all the dialogue available before the attack.
I did not do the Shadow Broker DLC but I could still have some choices, including having Liara talk to her but she no longer appears in the Citadel after the attack.
