I started out slow by doing push ups and now I go to the gym 6 days a week and it shows
Do you want to lose weight? Do you want to add some muscle? If you want to lose weight you still want to lift weights, because that burns a lot of calories. If you want to gain muscle, you don't need to do much of any cardio because you're trying to add weight.
The best resources are internet forums. rosstraining.com has a great forum on bodyweight exercises so you don't even need equipment (or at least not anything expensive) Ross has a great book called Never Gymless thats all about working out at your house. You can get all the info you need from forums for free, but a book just puts it in one convenient place. (I'm only mentioning rosstraining because there's a lot of BS out there and Ross walks the walk and I have Never Gymless and loved it)
