Hey Fredrik, welcome. it seems like a big task but you can do it. if you haven't worked out in a while, take a look at simplefit.org The guy that runs that site is a member here and designed the workouts for us n00bs :D
That should get you going. I did the Warmup for a few weeks to get the "kinks" out.
Do searches for what you are looking to know here as most questions regarding starting have already been asked and answered.
