As for the cost, it varies widely depending on the country, the supplier and the agreement a consumer has with the supplier. The lowest figures in 2012 are around $0.05 per unit rising to as much as $0.50 per unit in some countries.
Typical prices for the US are in the region of $0.11 per unit. In the UK, they are $0.12 - $0.20 per unit and in other parts of Europe, $0.030 per unit is not uncommon.
Prices are subject to frequent and large changes so the figures aren't reliable but are representative during 2012.

Copper and aluminum are the most common metals used for electrical wiring due to their high conductivity and relatively low cost. Copper is preferred for its superior conductivity, while aluminum is often used in larger, high-voltage cables due to its lighter weight.
If there is not enough slack to create a pigtail connection, you can use a junction box to extend the old wiring. Cut the old wire short, strip the insulation, and connect it to a new wire with a wire nut inside the junction box. Make sure to secure the junction box properly and follow all local electrical codes.
You can find basic home wiring diagrams in electrical wiring books, online resources such as websites or forums focused on DIY projects, or by consulting an electrician or home improvement store for guidance.

There isn't a good way to do that without knowing what you are building. Most good eletricians charge by the hour or a flat fee per job based on the type of work and working conditions. For example running wiring in a tall warehouse ceiling will cost more than wiring a new home thats still being constructed.
Generally, you cannot change wiring in a home with sheet rock without significant damage to the sheet rock. If you abandon the existing wiring, which is technically a code violation, you can drill through the bottom or top of each outlet or switch box into a basement or attic and rewire that way. Replacing lighting wiring in a ceiling without an attic above cannot be done without damage to the sheet rock. An alternative is to surface mount new wiring and boxes. This adds significant cost.

Not really. The amount and size of wire is governed by regulations in each country. Using thicker wire would produce slighty lower power losses but not enough to make it worth the effort.
