I tend to use different hardness of wire depending on what I'm going to make with it. For instance, soft wire is great for making spirals, half-hard is great for making angles. I don't use hard wire because it is very easy to harden the wire yourself, and if you get it too hard, it breaks.
Before I start a project, I run the wire through nylon jaw pliers. This both straightens and hardens the wire. After I've finished a wire component, as long as there is no bead on it, I sandwich the entire component between two pieces of nylon (plastic) cutting boards, then I take a hammer and whack away at it. The cutting boards protect the wire from becoming marred. Of course, if i want it flattened, then I use a hammer and anvil. In fact, my 10 year old niece LOVES to do this part for me!
Two great sources for new wire workers is WigJig and Wire-Sculpture. You can search for them on Google. Here's a great summary of when to use which types of wire on
