No, they're different things. "I'm talking to you" means I'm talking to you at this moment in time, right now. "To talk with you" is not complete on its own. - I need to talk with/to you - I want to talk to you. - I have to talk to you. You use the infinitive "to talk" when following another verb, like above. There are some exceptions, but they're usually more poetic (e.g. to know her is to love her, to love is to live, etc)

Talk with may refer to a discussion whereas talk to could mean that the person who initiates the talk has more to say and might not be open to further discussions.

It depends on the situation. I'm taking to you is the activity that is happening right now. Talk with is for the discussions between two or more participants.
