I wouldn't trust that thing at all. Spring compressors that use two independent compression devices tend to cause the spring axis to bend as you tighten one side more than the other. The hooks on this one are rather shallow and have huge potential to slip off the coil (they already tend to like to slide down the coils as it is). If it did, the compressor on that side would fly off, potentially at great speed, and its also possible that the compressor on the opposite side may immediately fly off afterwards. Not to mention the immediate expansion of the spring itself. Many kits that use two independent compressors use a safety mechanism that wraps around a coil on each end. Of course, the problem with small diameter coils is that the shock can tend to get in the way of these safety devices. Especially when removing the OE spring as they tend to be long, requiring a large amount of compression. Personally, I'd prefer something like this:

But it's rather pricey if you don't do many lowering jobs. But most of the smaller compressors do lack the ability to expand a great deal after removing the bearing plate. Which means if you didn't place the spring compressor with only enough coils to get the bearing plate off AND such that you've left enough room to fully expand the spring on the compressor, then you may have to recompress the spring and put the bearing plate back on, reposition the compressor and try again. Which is a particular pain in the behind with these cheaper compressors.
I usually just pop the OE springs, but I truly do NOT recommend doing it unless you've seen it done in a relatively safe manner. I've probably popped springs out of more than 10 cars when I was wrenching regularly with my friends and can personally attest to how much energy is wound up in a precompressed OE spring. Aftermarket lowering springs tend to be short enough that spring compressors are usually not even needed to get the spring on though.

If the spring is already installed onto the front shock, then no, you will not need a spring compressor...
