Both methods are fine. Sometimes, overclocking through the BIOS disables C'n'Q (on some motherboards).
Use the latest AMD OverDrive 3.0.2:
http://game.amd.com/us-en/drivers_overdrive.aspx
With it, you can set Smart Profiles. What that allows is for you to run different clock speeds based on the task you're running. Once you've configured an application to run at certain clock speeds/voltages in the OverDrive software, upon launching the application your chosen settings will be applied (like when launching a game). When you exit the application, you can run very low settings back again automatically.
That way allows Cool and Quiet to remain functioning too.

- Whats the best way to overclock? I overclocked by raising the multiplier (since i have a black edition CPU) from 13,5 to 15,5 and the Hypertransport ref clock from 200 to 203).

Best way to overclock that particular CPU is by increasing CPU and CPU-NB multipliers until you hit your stability limit. Keep the CPU temperature below 70 degrees and voltage below 1.55v (the maximum allowed safe limit).
After you've reached the multiplier limit, slowly increase the HT frequency by 1MHz until you reach a dead-end for stability. You've done well in following most of this.

- Is it best to keep the DRAM:FSB frequency to 1:1, i have 1066Mhz RAM?
|
DDR2-1066 performs slightly faster than DDR2-800, so it's best to keep it 1:2.66 as long as you can, which gives DDR2-1066. 1:1 will give you DDR2-400 at 200MHz HT frequency. HT frequency multiplied by divider equals RAM speed.

- I have a cooler master elite 331 midtower case, which CPU cooler do you recommend?

Zalman 9500/9700 coolers and Xigmatek HDT-S1283 are the best bang for buck for such a CPU.
