My suggested progression. Just a starting point. You have to think in terms of progression, like "How am I gonna make my workouts harder/smarter over time to reach my goals as I continue to get closer to them?"
-Light weights higher volume workouts 2x/week using manageable loads and impeccable form. YouTube, etc, for form. Light cardio as often as you can stand it. Walk the stairs...park farther away...etc.
Count calories and don't underestimate how much you need to lose weight (not a typo)...if you're losing 1-2 pounds a week, stick with that number. Could be a vast range, so figure it out!
(See: Tailor-made nutrition, for a great example)
*Then: Work in some mobility work and stretching (google or T-Nation search for mobility drills
-Gradually up your overall volume, add weight, progress...push your comfort zone safely. Do not necessarily stick with by-the-letter programs here, do what feels good and lets you progress performance-wise in the gym.
-Transition into a third workout, still lower-intensity and higher-volume. Sometime around this time, add in neural activation work. This is easier than it sounds. See Eric Cressey, Mike Robertson, Tony Gentilcore, etc, for ideas: glute activation (bridges)...etc, etc, etc. The neural activation work is VERY important!
You have to balance out those misused/disused/underused muscles under that blubber to get fit and healthy, let alone look good.
-Begin to regiment your intensity more, and by this time (I'm guessing 6-8 months from now, could be more or less though) you should really be impressing yourself as you've added a couple pounds a week to all lifts. Stay safe, but take it up a notch. Start playing with some heavy weight. Maybe cut your calories a bit more, maybe not - do what feels good and works. Heck, add in some HIIT if you need to.
To burn off your last 10, 20, 30, whatever pounds...go with some hardcore recommendations from Alwyn Cosgrove. Maybe even use a hardcore diet. Use HOT-ROX. Have fun!
Throughout this time, I would definitely recommend reading articles and maybe slowly applying the recommendations, but mainly go by what you feel comfortable with. This will be a slow, but effective process. You will know when you're ready. By the same token, don't listen to everyone who "knows what you need to do."
-Stick with the mobility and activation work, but shape your workout around what works regarding your goals. Despite what people may tell you here, it is
A) Possible to lose fat more quickly if you're obese
B) Possible to lose fat and gain muscle and strength simultaneously, especially if you're obese
C) Definitely possible to go from HUGE to lean and fit!
Some other ideas...
-Keep a training log. In your case, a food log would be good too til ya learn how to keep mental track (daily) of calories. Don't eat cheat meals. Use your log to track your weaknesses.
I would suggest doing whatever works, but transitioning to total body training, even "light" total body training, ASAP. Dan John also has some good "beginner" type articles (which, ironically, are good for 'most any lifter).
Oh, one more thing, don't get into this "I have to have a training partner/blog/significant other/forum/website/supplement/whatever to reach my goals." Your goals are for YOU. If it helps a bit, fine, but be independent and dedicated. Make this your lifestyle. You can do it. Don't anchor yourself unnecessarily to other people and then depend on them for your success.
