I honestly think it's a very good idea to address things that might possibly cause concern, and give reasons and explanations for each of them, if there is one and it's appropriate.
The ones that say "save us" in some form are the ones I have the best understanding of. (Some of them I can't answer at all yet.)
Firstly, we sing "Through the prayers of the Theotokos, Savior save us!" Sometimes that gets abbreviated down in various steps, the perhaps the simplest of which is merely "most Holy Theotokos save us". In the cases where we are really asking Christ to save us and to add the intercession of the Theotokos to that effect, I see nothing wrong. That's no different than someone who is struggling and asks someone else to pray that God will help him, and almost no one would object to that.
Sometimes too the 'saving" we request is not eternal salvation, but protection from harm here on earth. There is indeed a long history of such prayers to the Theotokos (Panagia), and many accounts of miraculous answers. Pairing that with the understanding of the Theotokos as already in a glorified resurrection body, and being that her life was essentially devoted to bringing forth the Christ, so she is intensely invested in seeing His work furthered, it begins to make sense.
And as someone mentioned, Paul even talks about himself as "saving some" ... and we don't interpret that to mean that Paul is anyone's savior or a co-redeemer in any way.
I understand most of those instances, based on one or a combination of these factors.
Other things I read I'd like to understand better. I may, as I run across them, ask specifically about. When I first encountered them, I wasn't able to discern how much weight the Church places on various things. And the source may be a bit questionable - I don't remember where they come from so don't know.
I'm most uncomfortable, for example, with a description I read where Christ was supposedly ready to act in vengeance and the Theotokos stayed Him. (Being that it seemed to mischaracterize Christ, I'm thinking this one might not be "official".)
But what we find in the Liturgy IS accepted by the Church, so it needs to be understood, or dealt with, etc.
I'm still working on it.
Because I am baptized Orthodox, I accept the Church's authority and I believe in the end I will find that she is correct, when I properly understand. Any perceived error I attribute to my own misunderstanding, and I've found that repeatedly to be true early on, which is why I'm able to accept it. However, in the meantime, with my lack of understanding, some prayers would violate my conscience, so I don't say them. I think that is wise, because in my misunderstanding, I think I would mean something the Church doesn't really intend to say if I pray them, so I hold off until I reach understanding.
But I do think it's very important to address these things.
