I started running after 15 years of almost exclusively cycling.
I like to log my fitness activities. I built a web app that I used to use to log my cycling. Rather than generalize it for running, I now use the Cool Running Log. It does a great job helping me track my weekly mileage and how many miles I am putting on my shoes.
Another excellent Cool Running resource is this table of what to wear at different temperatures. It's like my clothing guide for cyclists, but reminds me that runners don't have to dress as warmly as cyclists.
