Good luck!!
Personally I found this forum the best place. I got loads of tips from here, and runners world magazine. I built my whole plan around asics.co.uk
What I found really good was if you can build structure into your training, so you are going to go out x evening or morning no matter what the weather, try to do things so that you can avoid having excuses... Always have a spare set of running gear if you can afford it this way no oh my clothes are wet... i cannot go out. I'm sure you get what I mean, you need to be slightly selfish in this, and it doesn't take long, it's just getting into habits.
Try to get into the habit of having your longer weekend run, or even walk at the beginning but make sure your family are aware that you are going to be out for 2 to 4 hours on a Sat or Sun and that this is the way things are, I personally found the long slow runs really important, as they helped to build up my belief as much as anything.
Always remember the first month is the hardest, once you've got that out the way it gets easier
I found a garmin watch was heaven, it really helpded with my training, i got one with the heart rate monitor and as much as anything it was seeing over time how much quicker i was recovering that encouraged me. It is also really great for helping you to know how far you've been.
Some days you've only gone half the distance you plan and you feel shot, i think if I didn't have the watch i'd have given up on some of these runs and just said that's it. that will do, but having it say you've only done x distance at times kept me going :0
Also trainers!! try to get assessed for a decent pair, or as you've run in the past I guess you already know what sort you like, but do make sure your feet are comfy when your running.
