Running Help

I need some help from my blogging friends. I've always loved to run, but have gotten away from it in the past four years. Between each child, I started running again, but then found out we were pregnant each time. Now that we are done expanding our family, I really want to get back into it and meet some new goals that I have for myself.

I would love recommendations for the following:
Sports Watch/Heart Rate Monitor
Your favorite running shoes
Shorts for Summer & Winter
Tops for Summer & Winter
Treadmills
Motivational books
Favorite Training plans for 5K, 10K, Half Marathon, and Marathon

I currently subscribe to Runner's World and pull a lot of information and recommendations from there already, but I would love any additional input. Thanks!
