Most valiant?

The One Ring itself, when made, didn't aid power to Sauron: it was a part of him set aside, compartmentalized.

If this is the crux of your argument, then you are wrong; in letter #131, Tolkien states that "while he wore it, his power on earth was actually enhanced. But even if he did not wear it, that power existed and was in 'rapport' with himself: he was not 'diminished'". Also, the bolded part of this quote leads me to believe that Sauron's power derriving from the ring wasn't much influenced by the existence of the rest of the rings (if it were so, I doubt he would have allowed the dragons to consume power rings).

Why would Sauron's fea remain naked "everlastingly", if he were able to flesh himself again just in a matter of days, or years?

Because Melkor would probably not allow it.

And, as for Morgoth's scorn, do you think that Sauron, having cowardly surrendered his stronghold to a single female helped by a dog, saved himself from Morgoth's "disapproval"?

Apparently yes; he did became his heir after all. Not to mention that he would have been weakened (and dishonored) if disembodied once, therefore more worthy of scorn.

No, it is not.

That may be true about Sauron only after his third disembodiment. Sauron reincarnated himself twice, and at least once he did it without the help of the ring.

That was from the Letters you love so much

"Tread lightly, for you're stepping on my dreams..."

Gandald admits he will not be able to carry the Ring to Mt.Doom and destroy it. The temptation to use it will be too strong.

The decision to take the ring to Mount Doom was only taken at the council of Elrond; though you may be right about the rest.

He would have jumped into the fire, IMHO, his love for Frodo having nothing to do with it, and his love for the Precious - everything.

This clearly contradicts Tolkien's opinion on the matter. Have it your way.

I'm eager to agree with what the Gaffer said earlier -
Fatty Bolger, for staying behind to face the Nazgûl alone!
