which is better???

yea, seeing as how your ram is stable in the first option running at 225mhz i would estimate that your ram is currently running on the 5/6 divider so (256/6)*5= 213.3mhz.
your ram is running at 213.3mhz when your htt is set to 256 and when using the 166 divider.
so if your ram was stable up to 225mhz as in your first option, then you can carry on raising the htt using the 166 divider to 270htt where the ram will be back at 225mhz. beyond that you either sort out your ram speeds or you drop your divider to the 133 option and carry on raising the htt.

Not necessarily. CPU and RAM overclocks should be treated seperately as far as is practicable.
Try lowering your RAM multiplier right down, say to 100Mhz (1:2 RAM/FSB divider). At a core frequency of 256Mhz this will run your ram at 256Mhz - well below the rated spec for the RAM. This should allow you to continue to increase the core frequency and test the stability of the PC, but based only components other than the RAM.
Basically, you might be able to attain a higher CPU clock without damaging your RAM if you use a lower divider. Establish the highest stable clock for your CPU, and then try lowering the CPU divider and doing the same for the RAM. Once you know the stable ceilings for both RAM and CPU (assuming that this isn't limited by any other components) then you can figure out a suitable balance between frequencies and dividers.
RAM bandwidth isn't often a bottleneck in todays PCs AFAIK. You'd be better off with a higher core speed and a reasonable RAM frequency.

well like i said in my earlier post its best to keep everything running as fast as it can. and if you take his cpu into account an 3000+ its not going to go much over 2.5ghz without silly vcore at which point its probably better for him to back down.
his cpu stock speed shoudl be 1.8ghz using the 9x multiplier. a htt of 270 would give him 2430mhz core speed and his ram if he still uses the 166 divider should be running at 225mhz. 2430mhz is above average overclock for a 3000+ so first thing to do would be to clock up to 265htt and see how it goes from there.
if he can get higher then by all means lower the divider to the 2/3 divider which is the 133 option. 270htt with the 133divider will result in ram running at 180mhz. it does sound like a hefty drop but don;t worry because im sure you can tighten up the timings to get back some performance. and timings mean more than raw ram clock speed on A64 paltform.

I had my Venice 3000+ @ 2.66 (295x9) before I upgraded 
I was mightily impressed.
I'm also impressed with this 3700 San Diego I have now - it's currently clocked up to 2.97Ghz on air (Thermalright XP120), Prime stable and waiting to go higher!!! Altho tbh I'm scared to take it above 3Ghz
Not sure about the RAM tbh m8 but I'll be interested to the reply of others - it might help me to choose some new RAM (my Geil is unstable even tho it's never been taken beyond it's rated spec
)
