if i were you i would diet and do cardio. Wait till you lose more weight before you start weight lifting. Tredmill is a good start. Try 5 min walking, 5 min jogging, 5 min walking, 5 min jogging...etc. Also drink lots of water and clean up your diet also do not do weight lifting every day, 3-5 days a week would be fine.
My routine is a as follows
Monday: Biceps, back
Tuesday:triceps, chest
Wednesday:Shoulders, legs
Thursday:Biceps, back
Friday:Triceps, chest
Sat: cardio
Sun: rest
For now do cardio 3 days a week and once u start loosing weight then start pumping iron.
