not all spiders have the ability to build homes in their webs
Many spiders weave webs but not all do. Some spiders are ambush predators and do not build webs and still others actually chase their prey rather than relying on a web.

Different species vary - some spiders don't spin webs.. but it is not true that only female spiders spin webs - both male and female do - otherwise how would the male spiders catch their food?
Spiders that don't use webs to catch their prey are known as hunting spiders. They actively stalk and hunt down their prey instead of relying on webs to trap them. Examples of hunting spiders include wolf spiders, jumping spiders, and crab spiders.
Yes
Yes, all spiders have glands which produce silk. Not all spiders build webs (orb, sheet, funnel or otherwise) but they all have the capability to make silk.
If by "redback spiders" you mean the kind of widow spiders that grow in Australia, they make the same kind of three-dimensional tangled filament webs that all the member of their Family make. Some other kinds of spiders make orb webs, sheet webs, etc.
No they come from almost all types of spiders.
The reason spiders do not get cold is because they are not warm blooded like other animals with fur. The "fur" that you see on tarantulas and other spiders is not really hair but "bristles" and has nothing to do with how a spider keeps warm. The "hair" on a spider is used for several reasons. The hairs on a spider sense vibrations and a spider can tell a lot about it's enviroment from what it senses in theses hairs. Some spiders, like many New World tarantulas can use some of their hairs for defense. These urticating hairs are itchy and when a predator comes to close they shoot these hairs to make the predator go away. So, back to your question, how do they keep warm? Well, spiders are cold-blooded (actually, their blood is called hemolymph and is different from reptiles, etc). Spiders are the same temperatures as their surroundings and different species are adapted for different surroundings. when they are cold they will move to a warmer spot and if they are cold they will move to a warmer spot. Some spiders lay their eggs in Fall and then die and their eggs hatch in Spring. Other spiders dig burrows deep in ground and stay there all winter. The spiders that live in your house live there because the temperature is comfortable to them. Some people find spiders in their house and put them outside. This is not really a good idea because house spiders are adapted to live inside and can't survive outside. But, it's good to have in your house because they eat all insects like roaches, etc. that might carry diseases.
Well spiders that make webs only make the webs so that they can catch food; I'm presuming by 'hunting spiders' you mean spiders that kill in limb to limb action and/or biting/venom - these spiders kill stuff themselves and so don't need a web to survive... Survival of the fittest and shiz! Yeah that's just my opinion, but technically all spiders are hunters since they eat other animals ;)
Spiders live all over the world, but few are native to more than a few habitats. They are well-adapted to various conditions, but thrive in warmer climates (in Antarctica, stowaway spiders are dependent on humans habitations for shelter). Essentially, spiders are found everywhere except for on the Antarctic mainland. Surprisingly, spiders the size of dinner plates have been found on the seabed far below the surface of Antarctic waters. Many spiders spin webs in tree branches, but some live in holes that they disguise with their webs. Larger spiders, such as the tarantula, are free-hunting but generally only prey on insects.
