first of all .. its just a beginner lighting kit - nothing special .. i took a look and with the info that you have just a small room .. here my opinion :
They are using 45W CFL Bulb (3pc´s) = 135W total - thats quite the heat coming from this lamps in a small room. also not the best energy-saving option.
Umbrellas can be nice - but take a lot of space .. and they come with tripods - they have to stand ~ 1m from the wall ... small room will be full with that and the advantage of having soft light melts against the disadvantage loosing precious place.
i dont know the mesures of your room and what kind of lighting you are using - but its a plus that you know whats 3-point lighting - that makes already a good picture.
if you find someone wiring up 3 lamps i suggest going with LED Ceiling Lights (Daylight or Warmlight) :
1 * 24 Watt - 30 Watt
2 * 12 Watt
thats less than a half of the limostudio kit in energy. They come with frosted glas - thats gives you ~ the same effect like a umbrella - they produce less heat .. and they need just little space.
of course - thy need mounted at the wall not the ceiling
