Can this tree be planted outside, and if so, can we plant now?
It depends on where you live as to whether or not you can plant it outside. If it gets colder that 15 degrees F in the winter where you live, it will have to stay in a container and be protected in the winter. If it does not get too cold, plant it out in the spring, when you get the highest rainfall.
I have a Swiss stone pine with little white spots (scale?). How do I get rid of it ?
It is most likely scale, but could also be aphids. These articles will help:

I live in East Texas. I received an Italian Stone Pine tree as a Christmas gift. Do I keep this little tree in the house until spring or when do I plant it?
I would plant the tree out in a full sun location.
Make sure you water the tree well, daily for the first 2 weeks, then cut back.
Prepare the planting area as indicated in the link below.

Is it possible to cut back a Stone Pine tree and will it grow back from 'dead' wood? I have a need to control the size of one I have in my garden.
A Stone Pine can grow 40 to 80 feet tall and 20 to 40 feet wide.
Broken and dead branches can be pruned any branches that need to be removed to help shape the tree. Make the cuts at the trunk.
From my research trimming or topping the tree will result in multiple branching.

Wanting to grow an Italian pine in a pot in Athens, Alabama. Any tips?
Athens, Alabama is gardening zone 7 to 8, and this tree is winter hardy in zones 7 and above, so you'll be able to leave it outdoors year-round. It does best in full sunlight.
Italian stone pine can be kept in a pot, which will help keep it smaller. It will still need to be repotted in larger pots periodically. Use well-draining soil.
Here is general advice for growing this tree:

I have several potted Italian Stone pines that I would like to donate to a pet shop for habitat in a reptile cage. Are they safe for lizards and snakes in their warm, moist environment? Foolishly, I brought 5 potted trees to Colorado Springs... grrr.
I can't find much information as to whether this live plant (or pines in general) is safe for a reptile habitat, but it seems that pine shavings (and possibly pine needles) shouldn't be used intentionally as bedding for reptiles. Some owners think they release oils that can harm reptiles if they get on their skin. So, if the plant sheds a lot of needles, there's a possibility it could be unsafe for them. This link might help:

I have a Stone Pine tree {outdoor}. At first it was doing fine but now old growth is turning brown,I live in Georgia zone 7.This spring and summer has been much hotter than normal. Can something be done to same this tree?
Your pine tree is trying to save itself by turning brown, and there are several possible causes. You've probably increased watering due to the hot conditions this summer, but that's not necessarily the best way to keep the tree healthy unless you let the soil around the tree dry completely between waterings. There are a couple other possibilities as well -- this article may help you:
