Hi Terry,
Welcome to the community! 
My first question is, what is your athletic ability level? Because I don't really want to make suggestions that will cause you to burn out and such.
Now, the flexibility DVD, I would really suggest doing that everyday either by itself and/or as a cooldown. What I usually do, is I'll do strength training twice a week, metabolic conditioning twice a week, cardio and stretching everyday. I go through the flexibility circuit in 1 set instead of 2 sets most days when I'm also doing strength/metabolic conditioning, and the full 2 sets on my cardio/stretching only days.
And where are you planning on doing all the workouts? At home?
Depending on how well trained your muscles are will really depend on how you want to begin approaching your workouts on the TRX. For me, when I first started using the TRX, I just did the All Body XPress workout 3 times a week, and went hiking 3 times a week for cardio. That gave me a chance to get my muscles trained adequately. And then I ramped it up from there.
Regardless, I would definitely suggest doing some jumproping daily as a warmup/cardio in addition to other elements you may want to incorporate.
Thanks,
Justin
