The wife and I are both into bodybuilding (not at a competitive level, but just for fun). Once you really get into a good routine, you'll really enjoy the fruits of your work. As was said before, what is your goal? If it's just to loose some weight (by "toning", I'm assuming you mean look a bit more muscular), then it's 75% done in the kitchen. Calories in<calories burned. But don't overdo it. Don't starve yourself and try to do 1000 push ups. Maybe a few hundred calories less in than you burn per day is good. Also, what you eat is important. Your body needs a healthy mix of proteins, carbs and good fats. Chicken, brown rice, almonds, cottage cheese, greek yogurt, well trimmed red meat are just a few examples. Watch pasta intake, high in calories and very high in carbs. Stay away from heavily processed stuff...sugar cereals, etc... You may even want to try measuring your food out, just for a little bit, to help give you a good idea of portion size/control. For example, at dinner I'll eat between 6 and 8oz of boneless/skinless chicken breast, and about 3/4 cup of cooked brown rice. Until you measure it, it's hard to really know what that "looks" like. Not saying you should do it daily, but just try it to get some ideas.
As for exercises, lots you can do at home. Squats and lunges are great. Try holding something in your arms...grab anything you can. Several different kinds of push ups, pull ups, sit ups, etc... Don't do the same thing every day. For instance, don't do squats every day. Give whatever muscles you work a chance to rest. So maybe on Monday do squats and other leg intensive stuff. Tuesdays do push ups, etc....
