Your friend Google may be of some help here. Take a look at and if needed feel free to ask more help here. But post a link, as it is more easy to give help that way

You mean to draw them? There are various software that make timing diagrams, some commercial and many open source. I currently use TimingAnalyzer in the rare case I need to (although I used XCircuit for eBook articles).
