But I don't think that's the best program for your current situation.
By prioritizing and focusing all your efforts on one of those three goals for the short-term, you'll get further faster.
So, it's fine to have fat loss as your number one goal, and of course want to preserve muscle/strength and build it whenever possible, but just be clear that you are really talking about three distinct goals - dropping fat, gaining strength, and increasing speed - even though there will be some carryover between them.
Like lemonman said, one idea is to stick with the lifting program that's been working already and tweak your cardio and nutrition to boost fat loss. So I'd say stick to lifting mostly in the 4-6 rep range and fine-tune your cardio/diet as needed.
And on that note, I'm headed over to your other thread, about cardio training, to see what's what over there. (This is one of the problems with having multiple threads discussing individual aspects of your plan. They're really inter-related issues. Just sayin'.)
