The 135 watt QB is great for a 2x2 tent. I've been using a cheap lux meter to dim it down so that it has 30k-ish lux coverage for the whole tent. It actually goes up to 160w, according to my Kill-a-Watt, and I had a plant burn when it grew too close and got more than 60k lux. Also, here's a great post about using a lux meter to get plant lighting dialed in.
I haven't used an HPS light, but in a tent that small, the extra heat may be an issue. The QB doesn't put off that much.
Buy a light meter!
Give it 600 to 1,000 foot candles. Water as needed.
Amazon, for $20 It reads in lux, but it's an easy conversion to candle power. As noggin-scratcher said, they're called light meters.
If you can spend a few bucks, a light meter will help you get an idea of how much more you need: http://smile.amazon.com/Dr-Meter-Light-LX1010B-display-Luxmeter/dp/B004K0A7I6
My 2'x4' indoor setup has six T8 fluorescents and is pumping out about 12,000 lux. Different plants require different amounts, but I suspect you're not going to get much in the way of results if you are below about 5,000 lux. It's hard to have too much light.
Fluorescents are fine but you sometimes need several of them. Big tube fluorescent bulbs (T12) are the least efficient, T8 is better and T5 is best though initial price goes up with those. Generally, just a few decent T8 warm-white bulbs should be enough.
LED lights are coming down in price while rapidly improving in quality. My next lighting upgrade will probably be something along the lines of these models: http://smile.amazon.com/Apollo-Horticulture-GL100LED-Spectrum-Growing/dp/B00FGG1HDM
You can also wrap some mylar around your growing area to make sure any escaping light gets reflected back in and the plants get as much as possible. This is the cheapest way to increase your light absorption though it obviously is limited by the lights in the first place.
Things get more complicated if you're growing flowering plants (they are more particular about requiring certain wavelengths). But for growing garden herbs, edible greens, things like that, you can keep things pretty simple.
