The best how-to start (even though the link looks wonky) that I've found is here: http://doctormama.blogspot.com/2006/05/listen-up-maggots.html
And socks do make a difference. I recommend putting something like Aquaphor on your feet to prevent blisters. The correct clothes make a difference, too (you don't want to chafe.)
If your goal is overall fitness, I'd also recommend getting some dumbbells (you can probably find some at a second-hand store or off of craigslist) and google dumbbell exercises.
If your goal is weight management, lifting is much better than running. If your goal is general fitness, you want to incorporate endurance, strength, flexibility, balance into your routine. (But if this is overwhelming, just start slowly!)
Have fun! I've been running since 1995 and it's such a huge asset to my physical, mental, and social health!
