You did, I never argued my stance in this thread, argued against her stance, mainly her lack of a well defined existence, but from your description, you seem to include perceptual reality as part of existence which is unjustified.
Just gonna argue against the first two a little bit, she hasn't proven the objective nature of reality, that (I will assume she means perceived reality) the perceived reality actually exists in the first place, our perceptions could be wrong and not actually map out the actual reality. And secondly, it'll be hard to argue about the objective nature of it, if our only means of perceiving reality is through our unjustified perceptions.
The second point is also somewhat wrong, assuming her previous things, because that's not the only source of knowledge, we also have certain 'genetic knowledge' such as how to use our perceptions in the first place and certain genetic processes that are built in that have no use of 'reason' to them.

Does we have free will?
I'm not well read on the subject but from a brief intro long time ago, there were three major viewpoints on that, libertarianism who says yes, hard determinism who say no, and compatibilism which is a slight mixture of the two.
Is there a difference between an act and an omission?
Have to give an example to explain this one, isolate all things so that we are left with two choices and we pick one, lets call them A and B. An act would be choosing A or B. An omission would be not choosing A, resulting in B, or vice versa. Is there a difference? One example where this kind of thing pops up is during euthanasia, letting the person die or killing the person.
