Voltage stabilizes the CPU by increasing the amount of power available at the cost of increased heat generation. You get errors when you increase beyond a certain point simply because there isn't enough voltage supplied to the processor to fully execute all the commands that are requested of it, so they simply don't get processed correctly.
But yes, increasing FSB is usually the best way to overclock, however, you have to be careful with this as well, because with most rigs, you're not only increasing the FSB of your CPU, but it also has a direct effect on RAM and PCI clocks as well. So make sure you read up on it and make sure you're not taking your 800 MHz RAM to 1200 Mhz without realizing it and killing your RAM.
Most newer boards will tell you the clock speed of everything as you change it, but some don't, some don't even have options for setting the clock speed or multiplier of the RAM or PCI clocks.
But I also suggest you get a program like Everest or CPU-Z to tell you exactly what you get when you're in the O/S. Everest has sensors to monitor temperatures as well.
It's all about finding the right clock speed for your setup and cooling solution. You can play with voltage a little bit if your O/S seems a little buggy or it locks up, but I don't suggest getting too crazy with it. A small increase of .05 or .1 is a risk, but it's minimal, but once you start getting .2 or .3 difference it starts to get dangerous.
oh, and make sure you know where your CMOS reset button or jumper is on your board, cause you'll need it =)
