Overclocking the K7S5A is not really simple... you need to download a special tweaked BIOS to be able to change the FSB and/or multiplier.
Also I'm not so sure your chipset can handle FSBs up to 166Mhz... but you can always try.
The best stepping you can get is the AIUHB followed by the JIUHB. And yes the XP1700+ needs to be unlocked to reach the higher multipliers.

I think the NF7 only unlocks T-bred cores (like most nForce2 motherboards do). And yes you will be able to run your memory at higher speeds then default with that board.

Well the downgraded XP1700+ are factory unlocked for every multiplier of 12.5x and below... I'm not sure if they are unlocked by nForce2 boards to the higher multipliers but otherwise you only need to open one single bridge to unlock the higher ones. But they are very good OC'ers for sure.
As for your memory... ofcourse you know that CAS 2.5 will be always slower then CAS 2. Now when overclocking the memory in some cases the memory (factory CAS 2) can't run at the higher speed at CAS 2, but can handle the higher speed with a CAS latency of 2.5. So you wont get very high speed out of your memory but if Nanya makes decent memory you should be able to reach atleast 170-175 MHz with an increased Vdimm (memory voltage).

OK!
The choice is made! The XP1700+ it is!
But now:
If i buy the ABIT nforce mobo, what stepping for the CPU is the best?
These were the 2 I found on Excalibur PC. (I know they dont deliver outside USA but my dad has buisiness contacts who travel to holland often. I am gonna yse them as delivery boys )
AMD Athlon XP1700+ 1.47GHZ 384K 266 Tbred (TRAY)(JIUHB:0310WPMW) $72.00
or
AMD Athlon XP1700+ 1.47GHZ 384K 266 Tbred (TRAY)(JIUHB:0310XPMW) $72.00
The price is the same but what is the difference?
I know from: http://lowyat.isentral.com/guides/athlonxp/
what the M means and i am not too pleased with that...
Do you know where to get better ones or am I asking too much (unimportant) details and should I settle for these ones? (I think I know the answer to that already...)
Also: Do i need a new PSU? I have 320 W installed.. is that enough? I hope so... I am just a poor student... 
Greetzzz...
