Pickups
Starting with the basics, the standard strat design has three single-coil pickups. These are labeled number 6 in the diagram. The topmost one is the neck pickup, the middle one is just called the middle one, and the bottom one is the bridge pickup. The switch, labeled 5 in the diagram, has five positions available. By switching it to the top position (closest to the neck), this activates the neck pickup only, so that any sound picked up by the other two pickups is not sent to the amp. The next click on the switch turns on both the neck pickup and the middle pickup. The third position activates just the middle pickup. The fourth position activates the middle and bridge pickups, and finally the fifth position activates just the bridge pickup.
Hum
Since they are single-coil pickups, there is a natural 60hz hum that will occur whenever any single pickup is selected. Special humbucker coils are available which are wound in two different directions and cancel out each others' hum. Short of that, most Stratocasters have the middle pickup wired in the reverse direction from the other two, and whenever you select position two or four, the hum is cancelled out.
Tone
Meanwhile, the tone knobs also work in conjunction with the pickups, and consequently are affected by the pickup selector switch. The tone knob labeled 3 in the diagram works with the neck pickup only, so it is only active when the switch is in the first or second position. The other tone knob labeled 2 in the diagram will adjust the tone for the middle and bridge pickups. Having the tone turned up to 10 will bring out all the rich, clean tones from the pickups, but turning them down will mute the sounds somewhat. Experiment with these knobs to get the sound you are looking for. Naturally when the pickup selector switch is not selecting the appropriate pickup, the corresponding tone knob does nothing.
Volume
The knob labeled 4 in the diagram is for volume. Set this in the middle and adjust the amp accordingly, so that you can turn volume up or down directly from the Strat body.
Whammy
Screw the whammy bar into the hole in the bridge, labeled 11 in the diagram, made for that purpose. Don't screw it in too tight or it will damage the bridge. Leave it one turn from tight, so it will fall by itself when you let go of it. To use the whammy, press down or pull up on it. This will bend all notes that are currently ringing out either down or up, respectively.
Amp
The FrontMan 15 amp which comes with the upgraded strat pack is suitable for a practice amp, which means it's plenty loud for old fogies like me. The cord connects from the output jack, labeled 1 in the diagram, to the input jack on the amp. The amp has two main modes, selectable by a pushbutton on the front. It has treble and bass adjustments, too, but the dirty/clean sound is the most radical difference. Out, you get a clean sound; in you get something like the effect of a distortion pedal, great for that "Iron Man" powerchord sound. When out, the volume control works, when in, the gain and dirty volume work together for varying levels of distortion/loudness. The highest gain is the dirtiest sound, and of course the regular volume does not work in this mode, but the other volume controls that.
Rounding out the diagram
The remaining parts of the diagram are: 7, frets, 8, neck, 9, keys, and 10, headstock. Number 1 is where you connect the amp to the guitar, by plugging in the included cord. To adjust the tuning of each string, turn the keys in one direction or the other to get a higher or lower pitch until it is in tune. The included tuner helps with this for standard tuning. To play a note, strum the string(s) you want to sound, with your fingers in between the appropriate fret bars. Rarely, you will actually want to put your finger on the fret bar. Now go take some lessons.
