There is soldering involved? Cool! Nothing better than an evening of inhaling solder fumes.
Yeah, practice a lot with the soldering. Keep the heat low, and as soon as it begins to flow, remove the iron. Don't blow on the joint, for God's sake, its not good for it.
Check out this tutorial for soldering. Really, really useful from a known good source.

Incidentally, the Foreplay kit they refer to is a Do It Yourself stereo preamplifier that can be built from a kit.
