I didn't read the whole thread, but I am an avid jogger and figured I'd offer some advice.
First, stretch out before starting. Depending on your fitness level, start out WALKING, about a mile a day, then gradually move up to a slow jog for part of that mile, until you are jogging the whole mile. After a while (it might take several months) you can add on to that - mile and a quarter, mile and a half, etc. I also like to walk about 1/2 mile before breaking into a jog as a warm up, and I walk another mile or so (depending on the heat) as a cool down period afterwards. Listen to your body; if you have aches/pains then just WALK for a few days until you feel better - then ramp up to jogging again. Pushing yourself will cause an injury.
Pick flat terrain to start, and gradually work up to hills, uneven terrain, etc. Buy VERY good shoes - this is something you should spend good money on. I like the Nike Free's:

A good running shoe should be flexible; you should be able to fold the shoe in half so that the toe and heel touch each other without too much effort. A hard sole will not absorb enough shock and you will pay for it in your knees and back.
If you have any pre-existing knee or ankle problems, invest in a good brace. I have a horrible right knee and can't run without my heavy duty knee brace.
You don't have to run forever in order for it to be productive; if you only have the time/energy for 1 mile, then just do one mile. Don't feel pressured to do 3, 4, 5 miles just because you think you have to. Only do what you want to do; if running for an hour is boring to you, then don't do it! It defeats the purpose of being good stress relief if you are pushing yourself too hard. You can feel great and invigorated after a short jog just as much as a longer jog.
I bring my boxer mix; she's an amazing athlete. She really motivates me and loves it. Her and I usually do our jog then pick up the other dogs at the house for the cool down walk portion. Of course if you're going to bring a dog make sure you start them up slowly just as you did for yourself.
Have fun and happy jogging
