That sounds good so far. It is important to try to find exercises for all the major muscle groups. Quads, hamstring, inner/outer thigh, calves, bicep/triceps, chest/back, shoulders, abs and obliques (sides of the waist).

If you want to tone keep those reps at 10-12. If you want to add a bit of definition add some weight so that you tire at 6-8 reps. You do want some resistance but not too much. If you are not sure then drop the weight and see if it's too easy which if it is then add the weight back on. Going up a bit on the weights won't necessarily gain you muscle just more definition and strength. It takes a LOT of work to build big muscles and you simply won't do it just by lifting moderate weights so don't worry about that. Those body builders have to work and eat to get that big and it wasn't by accident.

There has been some research done that doing cardio AFTER your weights help to burn more fat.
