Here's my opinion. You have a little muscle, but I wouldn't worry about trying to retain it. I'd focus instead on only dropping fat via lots of cardio (6 days per week) and 6-8 small meals with emphasis on protein.
Too many people on these forums prefer to focus everything around maintaining muscle mass while cutting. That's fine and dandy if you're 10-20% while carrying a lot of muscle. I've seen some GREAT success from a few people just focusing on losing all that extra fat first, then shifting the focus to muscle gain. Unless you're really experienced or have a reasonable bodyfat percentage, I wouldn't try to do anything other than cutting bodyfat.
Weight training can/should still happen as well. You could do three full body workouts per week (M,W,F) keeping the reps on the low side to increase strength.. OR you could construct a circuit training course. A circuit could be something simple: squats, pullups, pushups, rest.
