You quit smoking? Good on you, Miz! As for the physical training, from your post I take it you're just looking to build back up to a solid level of general fitness. That is as opposed to training for an event like a marathon or for a specific weightlifting benchmark. It's a good place to start, but finding a clear and measurable goal you can train toward will help with motivation along the way (which you probably know, I just offer it as general advice to the group).
It's interesting that you don't like working out alone. At least for running, I prefer it and I know a few buddies with big families who really savor it. A long run is a rare opportunity to be alone for some folks. Besides running/jogging on the road or a treadmill, an indoor rowing machine is a great cardio alternative. What's nice is that you'll notice running speed and endurance improvements using the rower even though you aren't running. They can be a bit expensive for home use (~1000 USD/unit for the kind we keep at work), but any gym should have some available.
From the OP, I take it that a subjective assessment of muscle failure ("until I just can't do any more") seems to be your max reps/weight standard and your strength training is all body weight resistance. That's ok, but to build back some of that strength from your Army days faster, you may want to consider weights. Back squats, dead lifts, overhead press, and bench press will get more of those muscle fibers firing and will bring you more "whole body" strength than will plain old push-ups and pull-ups. Even if you're starting out with just the bar as resistance, these are great exercises. With good form, 3 sets of each at low reps (4-6) and ~90% max weight, and continuously rising weight (1-2 kg more on the bar every workout--assuming you keep on schedule!) you'll build real strength in your upper body, core, and legs.

You may also see better results (and less boredom!) by staggering workouts (as in, a cardio-heavy day followed by a strength-heavy day followed by an agility day then back to cardio-heavy) rather than just a routine of daily running and muscle failure "ups".
