Ok. Here's my 20 second schpiel.
If you're trying to lose weight, the ONLY thing that really, truly matters is diet. Period. You can work out if you want, to help create a calorie deficit, but the only thing that's going to help you lose weight is diet. And biking 9 miles a day probably isn't going to do much in the grand scheme of things.
Not only that, but unless you have a ton of weight to lose, it's unlikely that you will be able to build muscle while you lose weight. They are two separate processes. One requires a caloric deficit, and one requires a surplus. That is a mutually exclusive set of goals.
The big benefit to lifting weights while trying to lose weight is the ability to maintain the muscle you have and give your body the signal to burn up the fat instead (and this needs to be supported by a proper, high protein diet). Honestly, though, it's really not that horribly important. And even less so if you are just hopping around doing whatever.
So what should you do about your diet? Eat less. Period. It doesn't matter if it's fat, or protein or carbs, you just need to take in fewer calories than your body needs to maintain the weight you're at. About 10% fewer for healthy weight loss. Now, ideally you'd eat a high protein diet that is relatively low in "bad fat". At the end of the day, though, a calorie is pretty much a calorie.
If you really want to lose weight, you really need to find out how many calories your body needs and then eat less than that (or exercise enough to make a deficit). There are formulas out there that will get you fairly close, but the best way to find out is to keep a meticulous set of notes on what you eat for a week or two and weigh yourself before the week or two and after the week or two. Add up the calories and diivide the number of calories by the number of days. If you've lost weight, keep at it or subtract slightly (goal should be .5-2 lbs a week...no more), and if you're above it, subtract and try it again.
Cut way back on portion sizes and less carbs and more vegetables. Typical meal plan for me was a 1/4 cup oatmeal with a teaspoon of flax seed in morning. Dinner was 1 piece of bread with turkey, lettuce and light mayo, carrots and an apple for mid afternoon snack. Supper was about anything, but just smaller portions.
