Ephesians 2:8-9
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.
I see faith in the same way I see conduit. When an electrician is putting in wire he puts up conduit to run his wire through. Conduit is merely a vessel for the wire, and hence the power, that run through. The conduit is of no value by itself. Only when something of value is placed inside it does it "do" anything.
Faith is not a work. In a theological sense, it is the epitomy of not working. A person will only come to God in faith when he realizes he can do no work to save himself. My faith is of no value. I am sitting in a chair as I type. I sat down in it by faith. However, if the chair broke my faith in the chair would not hold me up. My faith doesn't work on its own. Kamikazes and muslim terrorists flew planes into ships and buildings having faith they would be rewarded. However, they think they are going to be rewarded for their deeds while the Bible says I am going to be rewarded for my faith. Not because it is of value, but because God says it is. He calls it righteousness.
Romans 2:2-5
"if Abraham were justified by works, he hath whereof to glory; but not before God. For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. Now to him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.

WORK, v.i.
6. To produce by action, labor or exertion.7. To operate; to produce effects by action or influence.
My works are incapable of producing righteousness necesary for my salvation. My merciful God knows that and has declared that my faith is him will be counted for righteousness.
So, we "do" faith, but it is not a work that produces anything that can save me. My faith will produce works of righteousness, but not "enough" to save me. In fact, the works produced by my faith will justify me in the sense that James talks about. It will "prove" that I am saved.

NOT WHAT MY HANDS HAVE DONE
Not what my hands have done can save my guilty soul;
Not what my toiling flesh has borne can make my spirit whole.
Not what I feel or do can give me peace with God;
Not all my prayers and sighs and tears can bear my awful load.
Your voice alone, O Lord, can speak to me of grace;
Your power alone, O Son of God, can all my sin erase.
No other work but Yours, no other blood will do;
No strength but that which is divine can bear me safely through.
You said "You try to have us necessitated to ‘do’ one (belief) yet not the other (faith). Again, I see that as simply inconsistent and confusing."
I am not sure I have answered this charge but I have tried. I have never really tried to address the belief verses faith issue. For this discussion, I think it is best to look at them as the same (For with the heart man believeth unto righteousness).
