I still plan on running, but I will never run more than 30 minutes and I won't do it more than 3-4 days a week. I up the intensity, not the time.
Pushups are great for a while, but pushups are difficult to add intensity too after a few variations (just adding more reps isn't very helpful). It's like any exercise, if you don't continue to add difficulty your gains start to go down.
My comment on lifting/resistance exercise vs running/cardio was not to suggest cardio isn't important, but that most people who "exercise are 90-100% cardio. A 2-5 mile jog a day keeps them "in-shape." It doesn't make much sense when you can get a lot of that cardio from resistance training if it's done right and the resistance training builds real strength.
I always fall back on a quote from a professional trainer at Athlete's Performance (train a ton of pro athletes). Someone asked him if he could only do one exercise for the rest of his life, "what would it be?" He answered, "Squats. Being able to run 5 miles won't help you get out of bed when you are 80." It's not an exact quote, as I haven't seen it for a long time.
It's the most important exercise you can do and, if done right, it can easily be a good cardio workout too. Even at very low reps.
Here are some really great fitness articles that highlight and provide more detail on my philosophy:

I'm not worried about the MMA gym. I have done high intensity sports before. No doubt it will kick my ass physically, even after I'm in shape, but it won't be because I should have done more cardio. It's just hard.
