(That doesn't seem short to me.)

I know and trust the Intels, but I can't say how they will compare.

Distro: whatever you are comfortable using. Any can do it.

CPU: 64-bit processors do not have the same memory address space 
limitation as do the 32-bit CPU's.

Kernel: if a 32-bit CPU, there are simple patches available which allow 
you to specify a LOWMEM / HIGHMEM split other than the default 1G / 3G. 
For 1G physical RAM, this is preferable to activating HIGHMEM. I think 
mine is set at 1.25G / 2.75G for 1G RAM.
