Well trot off back to your normal life Anna, don't let us get in the way of your television watching or whatever passes for fun in your world.
This might sound like ducking the question Adam, but if you have a Games Workshop near you just go in and ask the staff. They'll be happy to run through it with you, running demo games and combats is a big part of what they're paid for and they like doing it.
If that's not an option, then learn by trial and error - don't try to understand it just by reading the book, set it up and do it. That's the best way to see how it works. Start at page 8 and go through it line by line until page 18. There's a summary on page 22 once you have got the basics, which will remind you of what order things go in.
The game runs in turns. In turn one, you have a go and then (when you have finished) your opponent has a go. Then it is the end of the turn, and the next turn starts.
There are a set number of things (phases) you can do in your turn. You have to do them in order - if you forget to move a unit in the movement phase and then you start combat, you can't then say "oh, hang on" and go back and move that unit. So you need to think it all out in advance.
Once you have moved, including charges, you then get to shoot with any unit that is not already in a close-up fight. And then you resolve the fighting between the units that are in a close-up fight. Then you remove the dead, and it's your opponent's go.
Hope this helps. My advice is definitely to grab an opponent and get stuck in.
