64 BIt Question

[1018DADA]

We are debating wheather to use 64 bit version of Networker for our new server, following questions came up.
1. Can Windows 2003 STD server support Tread Level Parallism.
2. Can Networker do the above.
3. What are the benefit or drawback if any for 64 bit version.
4. During DR what if you need to replace 64 with 32 due to hardware limitation, can you recover original install.
5. Does Dual Core CPU perform better then single core.
6. Will Proliant 585 with two duel core CPU give adequate performace for 8 LTO-2 Drives.
Any ohter thoughts.

My question is: is "Windows 2003 STD" a real 64 bit OS?

No, from what i understand of it, supports 64 bit extentions.
MS does call it 64 system though.
