It would seem to make sense (to me at least) that you design your cardio workouts to burn calories instead of lasting a duration of time. To save yourself the trouble of figurin' a bunch of sh*t out, the amount of calories you burn on the treadmill is related to your weight the distance you run. A common rule of thumb (or at least the algorithm most treadmills use) is to multiply [your weight in pounds]*[distance in miles]*0.75 = [calories burned]. 3 miles (for me) is the minimum i'll run for workout, but I've been running for years. Right now you're doing ~1.5miles (about 200 Calories per workout), so I'd say your first order of business would be to work up until you can do 3 miles for a workout (about 395 Calories per workout)
2) I'm a HIIT whore. So my advice would be to try using a greater deviation between speeds, to create the HIIT style of training
1 minute @ as hard as you can go
1 minute @ 6 mph
1 minute @ a walking speed
Try that for 5 times around (15 minutes), followed by a medium-paced jog for another 10-15 minutes. I can guarantee you'll see a noteable difference by mid-April.
