The bitch tits probably isn't gyno, so I wouldn't worry about it. Lots of fat guys just have boobs and they go away when they drop the bodyfat. If you drop the bodyfat real low and you still have tits, then it's probably gyno, but for now, don't worry about it.
Cardio is ok, and if one is really overweight it is the only option, but if one is able, HIIT is the way to go.
A workout something along the lines of the following would be good for fat loss:
Monday:
Squats and chins 2x8
Tuesday:
HIIT with at least 8 100m sprints (shoot for 80-90% intensity). Do less if unable to complete this and just work your way up. DON'T do a 100% sprint! Sprinting is very damaging to muscles, so in order to maintain this workout you can't do 100% sprints!
Wednesday:
Pullups and dips 2x8
Thursday:
Same as Tuesday
Friday:
Benchpress and maybe some ab work 2x8
Saturday:
Doing some HIIT is an option, but it's likely pushing it with most people. If you can, go for it. Otherwise skip it and rest. "Active recovery." Some light cardio.
Sunday:
Active recovery. Some light cardio.
And as to diet for guys with a lot of fat...they can drop the carbs low and lose a lot of fat while sparing muscle. The Metabolic Diet would be a great way to go, IMO.
Supplements:
Cod liver oil - 1 tbs ED
You can skip the other supplements for now...this should be enough to get you to drop a lot of fat. Once you get lean you can use some supplements to help get you really lean.
As always, eat only whole foods.
