Im not familiar with the BIOS on gigabyte boards but one thing that is easy to start off with is disabling C1E, CPU EIST, TM2, from there you can start raising you FSB in small increments (IE 5mhz), this will also raise the frequency of your RAM which depending on your RAM may or may not be a good thing. Most motherboards have ways to either lock the RAM at a desired frequency (IE 800mhz) or change the multiplier (CPU FSB 200mhz would be 1:2 for DDR 800mhz RAM) as the FSB increases the "1:2" multiplier will have to be changed. Now as you raise your FSB you will inevitably have to increase your CPU's V-Core with this you should be able to get your CPU up at least 10% maybe more. Some key programs to download would be CPU-Z for checking your voltage and clock speed, RealTemp for getting accurate temperatures and IntelBurnTest to stress your CPU to know if your stable or not. That takes care of both RAM and CPU for now, if you can tell me the model name of your CPU it would help further. For overclocking your video card stick to ATI Tool and again go slowly, overclock little by little and do some testing as you gradually raise your clocks in 5mhz increments for GPU and MEM separately. Good luck and watch your temps.
