You've received some good advice. I may have some sniglets to offer...

Generally a good idea. However, I've installed cat 5 in a house where we
*had* to use the same conduit. I specified shielded cat 5 and grounded
the shield to the conduit at both ends; we've experienced no problems.
Note that the foil shield makes it more expensive and harder to work with,
but not prohibitively so.
Another suggestion is to spend the money to put in an RJ-45 jackpanel at
or near your server, and try to locate all this near where your telephone
service enters the house. There is a wiring scheme--aw, rats, I'll have
to look it up when I get home; I think it's something like T56-B--that
permits the cable to be used for either voice or data. I wired my
brother-in-law's office that way, and it's worked reliably for the last
6 or 7 years. You want data? Jack it in at the panel. Voice? Just
change the jumper.
I don't know where you live, but if you get the Anixter Cable catalog,
they have a surprising amount of very good background information and
suggestions for every section. That sucker is *big* and *heavy*, though.
