Do you want one of the two computers act as a gateway for internet
access? If so, it is recommended that you don't do very much on this
machine but firewall and IP masquerading. I don't know how powerful the
Sparcstation is, but I guess it'd be a little slower than the PIII
machine. So you make this the gateway running no services but the ones
absolutely necessary. All the other stuff, you put on the P3.

That depends on whether that site should be seen from the outside 'net
(well, probably ;-) ) and what you intend to do with it. Again, it
would be best not to expose more than necessary to the outside world.
So you put Apache on the P3 like the rest of it and directly forward
the ports for http (and probably https) to that machine; same thing
goes for the DB server except you certainly don't want anyone to access
it from outside. As long as the database and the number of hits stays
low, the P3 can easily handle it alone.
Of course, if you plan to run something slashdotesque, a little more
oomph in form of separate server machines wouzd be needed... And a good
inet connection, last thing I heard slashdot had an average bandwidth
use of 38Mbit/s. But those dimensions are a loooooooooong way down the
road. Doing it "right" is not cheap and most of the time just overkill,
but interesting.
