Good beginner at-home workout equipiment?

I have been doing the bodyweight and pilates / yoga / no-equipment workouts for a few weeks, and I have a set of 2lb barbells, a pilates "magic circle), some exercise bands and a foam roller. Now I want some slightly heavier weights to do more of the weight-bearing workouts - what's the best setup for a beginner? 43-year-old woman in reasonable shape (I hoist 50-lb kids all the time no problem!)
