After P90X3 (4 weeks to go)

I am pondering what to do after P90X3. Here is my story at age >40:

Last fall, I did 8 weeks of P90X and lost about 10lbs. The holidays hit. I failed to finish in part because I wasn't able to spend the 1.5 hours it required from start until showered afterwords. Lost 15lbs and a waist size that has stayed off.

Then, P90X3 came out with 30min workouts! Got it in December, started in January. Got through 8 weeks, got a cold and didn't finish. Last week of April, I started P90X3 again. I just completed week 9 tonight and I am determined to finish the next 4 weeks. So far, I have lost another 15lbs I am nearly down another pant size. I have another 20lbs to go to hit my target weigh and believe I will be able to do it by the end of victory week.

Beside P90X3, I have a 25 min robust walk I take as part of my commute home 5 days a week. On weekends, I try to get 1 hour walk in each day.

My diet is untracked, but I am currently eating around 2 - 2.4K a/day. I do allow myself the occasional crappy meal. But for the last 3 weeks and the next 4, I am definitely watching it more closely. I don't add salt, I avoid proceed sugar but probably could have eaten few refined carbs (I don't now). I recently bought a Forman grill and working on whole foods only with the following exception: I get and eat protien bars. However, I try to stick with ones that do not contain refined sugars and certainly no fructose. The Whey and Casein are free of additives and surclose. I get BioChem natural Whey and BodyTech natural Casein. The BOdyTech Casein was the only additive free one I found on the market.

The pluses at this point:

+Down 30lbs for the year and 1.5 waist sizes. In fact, people are noticing I have lost weight and my current clothes are looking baggy and I can use a new belt emoticon
+I can now do 15 normal, 15 wide, and 12 military push-ups from my perfect-push up stands. When I started, I could to 10 each from my knees.
+My blood pressure is down.
+My heart recover is quicker following the work out.
+Can do all the plyo pushups now.

The down sides:

+ I cannot do any unassisted pullups/chin-ups. However, I was using bands and was limited to #53 of bands (bodylastic brand) due to my apartment. I stopped using the door pullup bar when it came off and hit me in the head. My door frames in the brown stone are simply not good enough. However, I bought a Trapeze Riggings Elite XL pullup part an started using it week 6. If I had that at the start of this round, I suspect I would be able to do at least some unassisted pullups.
+I am not getting the lean muscle mass look I want. However, realizing I am losing weight first and also I needed to take in way more protein than I had been, I am not frustrated with the program. Just not realizing I needed more protein. Starting about Week 5, I added 30g of protien via Whey to my post work out and now consume 24g of protein from Casein at night. I am getting at least 110g/day.
+Also, about week 6, I changed from Bodylastic bands to the Powerblock U70 Stage I dumbbells.

Overall, I am not unhappy and have made a lot of progress. However, I would like a six-pack under my shirty instead of a bag by the time I turn 50 (I will be 47 in little more than month).

I am thinking about starting Body Beast Lean after P90X3. I don't necessarily want to look like the hulk, But having a full head of hair that is the envy of Woman in their 20s, I'd to have a more sculpted physical.

What do you all think I should do next to achieve my goals beyond losing weight and getting functionally fit? Body Beast?

Also, I suffer from Psoriasis and my chest and back are covered with blemishes. I will not publish photos.
