I got my crimp terminations & tool for small diameter wires from Pololu

While this thread is quite old, but, as a total noob to the world of Arduino and similar, I've spend hours googling and searching forums for this basic information. While most peoples here just do know this type of information, noobs like me just don't know this information, and it's not easy to find.
Information such as;
- if I want to make a jumper, what termination do I use?
- what are Arduino board terminations standards?
- how do I order termination pins and sockets, if I don't know what to order?
- how do I terminate the pins and sockets to the conductors (wires)?
- what size of conductor (wire) do I need?
- what do I order for termination shells, blocks, headers?
- is there a standard for wire colors, if so what is it?
- and other questions I should know to ask, but don't know to ask yet about Arduino header, connectors and interconnection hardware standards...
Other words, be nice if this information was sticky'ed. 
Thanks CrossRoads again!!
