How to for an updo?

I really want to do my own hair for my upcoming wedding (I hate going to the salon, it's like going to the dentist for me), but I'm not sure of the step-by-steps. If anyone is good at these things, look at these pics:

I want something like one of these- what do I need to know?

My hair is long with a slight wave.

Thanks for any help!
