This is just how I would work things and keep in mind I know everyone has different approaches....
It sounds like your body would respond beeter to a volume style training than and HIT or high frequency plan (correct me if I am off there). I am basing this on what I have seen in those with long limbs and a pretty tall. It seems these kind of guys can sling away with volume and grow but when they go to HIT style they don't pack on as much.
As for cardio, I would be more in favor of HIIT for 20 minute post workout. During your workout drink an EAA/BCAA drink to help with recovery and this will not interfere with cardio.
With your meals, I would drop the orange juice. I feel it is a waste of kcals to drink fruit juices unless you extract them from whole fruit. In fact, take all carbs out in the AM and focus your carbs pre and post workout, or just post workout.
I would also spread out your fats a little more (not sure how lean the steak is, but tuna is almost no fat). Use your meals around training to focus on recovery and growth and the rest of your meals to focus on fat loss (low carb, high protein, moderate fat).
Hopefully that helps a little....
