For all that you wrote, I still didn't see the words "free-will" in any scripture verse. I am not saying you don't make choices. I am saying the choices you make do not come from a "free-will".
"Free-will" implies that man is free from any outside influence. That is simply untrue, according to scripture.
Jesus says in John 8:34, "Truly, truly, I say to you, everyone who commits sin is the slave of sin." and 8:36 "So if the Son makes you free, you will be free indeed."
Romans 3:23, "for all have sinned and fall short of the glory of God."
Therefore, according to scripture, all are slaves to sin outside of salvation in Christ. A slave does the will of the master who owns him. If you are slave to sin, then you obey sin. If you are a slave to Christ, you obey Christ.
By the way, the idea of "free-will" is the oldest lie of Satan. What was the tree in the garden? The tree of the knowledge of good and evil. Eve thought she would be wise to discern good from evil. The implication is that she would be able to choose the good over the evil, of her own "free-will". She and Adam rebelled against God, they wanted to make "free-will" choices, and the race of man was enslaved to sin.

I know you didn't address me, but I hope you don't mind my offering an answer to your question, "Why do we need to do anything."
Because we are slaves to Christ, and He told us to. We obey the Master who owns us. We are part of His plan of redemption, and it is for our benefit and the benefit of those who will believe unto salvation.
peace to you
