Wow an outside centre pretty much just ran around a prop wasn't entirely Healy's fault is actually as defensively sound as a prop can get. Look up his hit on Kaino for example.
That isn't what happened though, and I re-watched the game a few days ago. Healy's attempt at a tackle was just aweful. He went high and just tried to grab Davies with flailing arms, Davies just shrugged him off to score. If Healy went in with the shoulder, he should have made that tackle.
Maybe I'm being a bit harsh on Healy, but not too many people other than the Irish reate Healy all that highly. As I said, good in the loose, but not the best (although improving) in the scrum. I think he'll be a great player in a few years, with time to mature (as most props need), but there's plenty of props I'd have instead of him. He should be viewed as better than Gill, simply because Gill is a relative rookie, but on the day I don't think ther'll be much difference between the two.
Adam Jones will still put Healy through the mincer..... Oh and Coonor, plenty of props have had 'storming' games against Austrailia.
I think your round-up of the combinations is pretty fair though. I do think Wales will have the dominant front-row, simply because Adam Jones is better than anything Ireland have to offer and will force a couple of penalties at the scrum. The rest I probably agree with. Backrow is quite even, because iven without Lydiate, Ryan Jones is in excellent form. Faletau has been in top, top form for the Dragons. Warburton has been a bit up and down, but has pulled out the big performances in the HC games, and I think he'll have another strong game tomorrow.
Very little between Priestland and Sexton, but Phillips has a significant advantage on Murray who's still learning. Back three I probably agree with. If it was North, Shane and Halfpenny, I'd give it to Wales, but Cuthbert (whilst big and very quick) is inexperienced and could make some mistakes. Kearney is in excellent form, but Bowe has dipped significantly from his world class form of a couple of years ago. Trimble is good, but not excellent. Still a slight edge to Ireland is fair with Cuthbert so inexperienced.
