Computer build questions

I am building a computer with the following components.

CASE           CHENBRO - XPIDER PC61166 WITH A 92mm FRONT FAN AND A 120mm REAR FAN
Main board     SOYO SY-P4I875P DRAGON 2 PLATINUM EDITION  
SYSTEM MEMORY     CORSAIR TWINX512-4000PT                    
CPU INTEL P4 CPU 3.0 GHz 800
HARD DRIVE WESTERN DIGITAL SATA 36GB RAPTOR
HARD DRIVE WESTERN DIGITAL SATA 250GB
VIDEO CARD RADEON 9800 PRO 256MB
LITE-ON 52X CDR DRIVE
SONY DRU-500 DVD WRITER
LITE-ON DVD ROM DRIVE

The questions I have are how big of a power supply should I use?  I have a new Antec 350W PS that I bought for another computer but never used it.  How fast should I run the front side bus?  
The system memory will run at 500MHz DDR or would 400MHz be better.  What bios settings should I use for best performance?   please include all bus settings and processor multipliers and any other settings that would help me build a fast stable system.

350W should be enough.
but make sure the case and the adapter is well ventilated.
As far as the memory goes, DDR memory runs as half of the DDR rating. This memory is rated at 500mhz, so the bus will run at 250mhz

Not necessarily so . . .  depends on the motherboard.  On an AMD system you'd be using a different bus speed.

The other thing to keep in mind is that systems work best when the memory bus and cpu bus speeds are synchronous.  Attempting to run them asynchronously (if you can) actually results in poorer performance, as many articles have shown.
