1. I'll reiterate the advice not to cook the stuffing inside the cooking. Whatever cooking method you use, just make a turkey stock, use that to make the stuffing, and cook it on the side. This is the way to go.
2. Sous vide is a really good way to cook a turkey... it's basically infra-poaching, and the results are excellent. If you want to be geeky, you'll want a PID controller and an immersion circulator... these are getting easier to obtain (non-contaminated from labs), and home appliances such as the Sous Vide Supreme are now readily available & affordable. Personally, I use a FoodSaver vacuum sealer and a Sous Vide Magic controller in combination with a large old-school asian rice cooker (simple on/off switch), and it works great. You can also just get down ghetto-style, using zip-lock bags and a digital thermometer:

Here's a basic procedure: Skin the turkey; reserve. Butcher the turkey, reserving giblets, legs, wings, boneless breast. Chop carcass with a meat cleaver, roast, make turkey stock in pressure cooker. Stretch turkey skin & press flat; salt & dehydrate. On Thanksgiving day, vacuum-seal legs & breasts separately. Make dressing of choice using turkey stock; bag separately from turkey. Cook legs at 150degF for 3hours, then reduce heat to 140degF, leave legs in, add breasts and stuffing, cook for another 2 hours. Meanwhile, deep fry the turkey wings. Crisp up the skin in the oven & serve right out of the oven, sliced into chips, alongside the meat.

4. Oven cooking: Whoever said to brine the turkey before cooking it sous vide... don't do this. Brining turkey works really well for oven cooking, but it's unnecessary (and can be counterproductive) for sous vide cooking.
America's Test Kitchen has published a whole list of tips for roasting a turkey. One year my brothers & I started drinking heavily at 10AM, and wound up doing pretty much all of them. We brined the turkey, then loosened the skin & rubbed garlic herb butter all over between skin & flesh, as well as outside the skin. Then we prepared ice packs & applied them to the turkey breast for a good 45 minutes before it hit the oven, so that the temp differential would give the legs a head start on the cooking. We started the turkey out supine at lower temp (I think it was 325degF), with a tinfoil heat shield over the breast. Then 1/3 of the way through the cooking time, we flipped the turkey into prone position and increased the temp to 375degF. Then 2/3 of the way through the cooking time, we flipped the turkey onto its back again to brown the skin of the breast. Then we let it rest a good while before carving... and yeah, stuffing was cooked on the side.
This was a good turkey. It was a lot of fuck-with factor, but we were drunk and in a mood to fool around; it was fun.
5. Carving turkey: Remove the wishbone in situ, through in incision at the front of the breast by the neck. Then make a midsagittal incision along the sternum, and take each side of the breast off the carcass entire. Slice the breast along the bird's length, from head to tail, against the grain. When you take the legs off, make sure to dig for the pocket of dark meat called the "oyster" just behind the leg joint, back of the kidneys - best meat on the whole bird.
Happy Thanksgiving everyone.
