When installing FreeBSD, and looking for the most reliable - stable setup, on an Intel machine equipped with an Intel board and quad core Xenon, (to be used an an internet server), should I install the 64 bit version or 32 bit version? Most, if not all the internet daemons will have been written in 32 bit. Will they run at all?

All depends on what you plan to host on the server and how much traffic the server will receive.  

Note:  32 bit daemon's can have problems with log files > 4GB.

64bit will imply NX memory protection.
32bit may or may not have it.

also 64bit is critical to directly address >4GB from device drivers. (but probably your ram is 10x faster than all IO devices together and bounce-buffers are not a problem)

Yes, FreeBSd amd64 provides compatibility for running i386 binaries, even oracle form Linux if you want). Say OpenBSD does not...

For stability - run memtest86(+) for as long as it is possible. in warmest corner of your office before putting system into production.
