Some thoughts as I read through it...
1.) I much appreciated the literal translation "drag"!
2.) I don't have Talbott's book handy here, but I recall his three prima facie positions being a bit more nuanced than that. Regardless, (c) must be modified to feature a proper counterpoise to position (b), such that God for whatever reason does not have the power to redeem certain people. (This, roughly speaking, and as you correctly note shortly afterward, is the Arminian soteriological position. Calvinists by contrast would tend to agree that God does have the power to redeem anyone He chooses to redeem; they would deny (a) in some significant fashion instead. As it currently stands, though, you only present the Calv version of (c).)
3.) Nice eye-for-an-eye maneuver.

The other points are generally good, too.
4.) The 'chrestos' term had connotations of 'healer' in 1st century Greek, btw; which is why authors sometimes used it as a pun with Christ or mistakenly thought that the two terms were identical. They're very closely related in any case, since Xristos means anointed one, and xrestos means one who anoints with a plaster for healing. The plaster would be sulphuric or mustard, and so be yellow (the more direct meaning for xrestos, or 'golden'); it would also smell terrible.

But it would kill the infections and save the person from death. Sound familiar to any biblical language?

At the same time, because of its connection to gold/yellow, xrestos also connotated the sweetness of honey. (Which is what the 1 Pet reference is talking about.)
5.) Heck, agape is even greater than hope!
Anyway, lots of good points in chp 2.
To chapter 3, I would add the observation that in the final chapter of RevJohn there is clearly a river of life flowing from under the throne of God and out those never-closed gates (the river of life being itself a symbol for YHWH and especially for the Son), so that the Spirit is encouraging those who are still outside the city and still loving their sins, to drink freely of the water without cost, slaking their thirst and obtaining permission for entering the city and eating of the tree of life (the leaves of which are for the healing of the nations). Moreover, the saints of the church are exhorted by the Spirit to join in this encouragement of witness to the (currently) impenitent sinners outside the city.
Also, I agree with Gregory (and other commentators) that the term in Thessalonians means whole-runination; but I also agree that the context doesn't necessarily imply ED. As I seem to recall Gregory himself mentioning, God promises in the OT to restore Israel from its own whole-ruination (same term used in the ancient LXX translation) after they've learned their lesson. So whole-ruination isn't the end of the matter.
{{But God’s loving attitude towards everyone is not an ongoing process}}
Slight correction: it is not
only an ongoing process. (It's that, too.

Good article! My one major contribution (other than pointing back to some of the OT contexts, which are also highly universalistic in context), would be to emphasize that the intrinsic nature of God as love is exclusively connected to trinitarian orthodoxy. That is, only trinitarian (or at least binitarian) orthodox theism can coherently say that God (singularly) is love (a coherently beneficial interpersonal relationship); and God's intrinsic self-existent essence as such involves theological corollaries leading to the kind of universalism you're talking about--and not to any other kind of soteriology (including not to mere wussy universalism where sin is of no account.

)
Orthodox universalists are still lagging behind in connecting solidly to this topic in such a fashion.
