The flux is almost always part of the solder (in the middle) - so using too little or too much flux usually cannot occur. Solder balls are cause by not heating up your surface well enough before using the solder. Proper soldering techniques require that the surface being soldered need to be heated to above 700F before applying solder, and then allowing the solder to flow. Taking the heat off too fast will cause the solder to coagulate.

semimba2006 has it exactly right. The only thing I would add to his answer is that the trick to knowing when the work pieces are hot enough is to let THEM melt the solder rather than letting the iron melt the solder. That is, touch the solder to the opposite side of the wire/pin/whatever that the iron is touching. When the pieces are hot enough, they will melt the solder. Immediately after the solder melts, it should quickly flow and cover the joint by itself and you can immediately remove both the iron and the solder source.
This sort of presumes you're soldering electronic stuff. If you're soldering copper plumbing pipe (usually this is refered to as "sweating" rather than soldering, although it's the exact same thing), then you do need to apply a separate paste flux to the parts before heating them. You can't really use too much flux - it won't keep the joint from sweating properly, but it is a waste to use more than enough for a thin coating on BOTH surfaces. As before, apply the torch flame to one side of the work and the solder to the opposite side. When the work is hot enough, the solder will flow into the joint.

Slow down! You also may need more flux. Are you heating the part then applying solder, or placing solder against the iron tip? Heat then apply!

The bread trick works. I have used it many many times without any problems. I guess you could use too much, it only takes a small amount, about a quarter slice or less. You do have to be patient and give the pipe plenty of time to drain. Be sure to open a faucet to let air into the far end of the pipe so it will empty out. Also, be sure to cutoff the hot water heater supply at the valve near it if you are working a hot water pipe.

Use less solder.
