Perhaps the advice on taking the bird from the fridge and "warming it" should be expanded on...
We want the whole carcass to be at a consistent temperature, so it heats and cooks predictably and correctly...and I'd suggest longer than an hour, though you'll want to cover it!
The advice that jennyma gives on a meat thermometer is spot on the money! Relatively cheap to buy, this is the handiest kitchen tool I own...I'll get rid of my Chef's knife before I lose this! Your meat probe can be used to test the breast, thigh and stuffing temp's and tells absolutely when you are done...
Note that when you remove the bird from the oven, leaving it stand, tented in foil, will allow the temp's to increase ten degrees F...so you take it out with the breast about 150-155, and so on...otherwise, it'll be dry...
I've written elsewhere about "flipping the bird" and relatively easy ways to do so...I'd recommend about 90 minutes of brest down cooking, then the "flip"...I use big skewers to suspend the bird over the (greased) pan, so the bird is not stuck to the pan (use little skewers to jeep the stuffing in!), so I can grab one skewer in my oven-mittenned hands, and quickly flip it end to end, dropping it back onto the roasting pan rim...this technique cooks the dark meat faster (which it needs to be so the white doesn't dry out)...it is necessary to flip the breast back up with adequate cooking time remaining for it to brown...other wise its that flaccid white, that you DON'T want...
Do have fun with this, pooch, and remember that a "juicy" bird is not an undercooked bird...a dry bird is an overcooked one...and if you use the brining, or "beercanning" (in Audeo's description, "tamponing"...sheesh those Texians!) it will be even juicier (but stuffing on the side, only!)
Lets all know how it comes out for you!
