There are two general approaches to making chicken juicy in the oven. The first is to cook a short time at a high temperature. For example, Barbara Kafka's recipe for roast chicken
calls for cooking the chicken at 500 degrees F for less than an hour.
The second option is to cook at a low temperature for a very long time. This recipe calls for cooking for an hour at 250 degrees F, with a high heat sear at the beginning and end of the time. Even more extreme is this recipe, which cooks at 140 degrees F for 4-6 hours. However, low heat will not give the yummy crisp skin.
Neither of these requires flipping the chicken.
However, if you really want the crispiness of the skin, flipping is the way to go. Two recipes from Cooks Illustrated (one and two) both call for high heat and a couple of flips. (As does Barbara Kafka's recipe for cut-up chicken, which I make all the time. Season the chicken, and put in a 500 degree F oven for 10 minutes, flip, 10 more minutes, flip, and 10 or more minutes or until the skin is crispy.)
If you want to go with the classics, Julia Child's recipe for roast chicken from also calls for turning the chicken onto different sides. She also bastes frequently, although the above recipes don't call for it.
The secret to really crispy skin has everything to do with rendering the fat that lies directly under it. Once that fat has removed itself from the skin, a little high heat will crisp it up perfectly. If I am creating a roast chicken, I normally remove it from the packaging and allow it to sit uncovered in the fridge for at least overnight, longer if I have the time. Then I start the chicken low to render the fat, you have to cook it at a minimum of 178F (80C) to remove the most fat. Once the fat renders out, which is going to vary depending on the temp you start the chicken at, you crank the temp to the 450 to 500F range and baste regularly.
To maximize the skin that will crisp you want to make sure that your chicken isn't sitting inside the fat while it cooks. I normally use a inset rack to keep the chicken above the fat but you don't have to. The other component to crispy skin is cooking the chicken uncovered.

As far as smoking: Use a roasting rack in the pan, and put enough water in the pan to not allow the dripping fat to burn. Keep the chicken above the water and check the water level during roasting.
As far as the liquid exuded: Be sure that you are using a chicken that has not been "pre-basted" (injected with a flavor/sodium solution). Slash the skin of the chicken, especially the dark meat, before roasting. That will give extra liquid an avenue for escape. Don't slash the breast meat, as that will likely dry out the chicken before it is done.
