I'm training to ride STP in July with TNT, so I've got a good handle on logging the miles/hours on the bike. I'd like to add some strength training and hopefully lose some weight over the course of the next 6 months and was thinking about incorporating Body for Life into my training program.
I've done it before and really liked everything about it. My question is, do you think that they might be counterproductive in conjuction with each other? Also, would you simply substitute the cycling I'll be doing for the cardio in the plan or do the HIIT in addition to the cycling training?

HIIT and regular, endurance-type cycling are very different beasts. I'd be tempted to swap out half of it: that way you get the time-friendly and BfL-friendly benefits of HIIT and you also keep your endurance fitness, which you'll need for that ton.
Alternatively, work out a HIIT-style interval workout you can do on your bike - which sounds to me like a short, tricky hill circuit to fartlek around. On-road miles are more useful than turbo miles, but you know that already.
The event you're training for is your first century, right? It's easier than it looks from this side. Between now and the even, build up some mileage rides, from whatever you're currently doing up to 70-80. As well as building endurance this builds your ability to sit on a bike for a long time (mind over ass), and it'll inform you as to what on-ride nutrition works for you.
