Debbie: Starting The 2nd Block of P90X

I'm still eating pretty much the same as the last few weeks. Now, I'm starting the 2nd block of P90X!
For week 5 the P90x workout schedule changes yet again.

P90X Workout Plan Weeks 5, 6, 7
Day 1 – Chest, Shoulders and Triceps, Ab Ripper X
Day 2 – Plyometrics
Day 3 – Back and Biceps, Ab Ripper X
Day 4 – Yoga X
Day 5 – Legs and Back, Ab Ripper X
Day 6 – Kenpo X
Day 7 – Rest or X Stretch

Plus, this week I'm going to the gym for cardio Mon, Wed, Fri for 30 minutes. Second week I'll bump it up to 1 hour and the fourth week I will do an hour plus add the 10 minutes of running/walking on the treadmill.
Anybody have an better ideas? I need to win this thing!! ;)
