Don't have a file server on the same box as the router/firewall - it makes
things very unsafe and complicated. Either get a separate machine for file
serving and use a firewall/router like IPCop on another box, or just use a
DSL router as a gateway. That's what's normally done, and it would be easier
to set up (most DSL routers have a nice easy web interface for this which
usually just need your ISP's login info), whereupon you could probably just
forget about it. It could also double as a DHCP server.

Probably not as easy as using a dedicated DSL router, although IPCop is
pretty easy and it's free (but you'll have to pay for a box to run it on of
course, and may need a couple of IP addresses from your ISP, depending on
how exactly your connecting to the DSL line).

No. Samba is for serving files to Windows boxes. Run that on a separate
machine.

It might get a little complicated at this point. I assume you're not using
Active Directory since you have Win98 on the network though. Samba can act
as a primary domain controller no problem, but getting it to authenticate
clients on the network may be a little tricky for those new to Linux. A
quick google on "Samba primary domain controller authenticate" shows this
which might be useful to you:

One thing you should also note is that Linux permissions are not as
sophisticated as Windows ones, so if you're doing stuff like setting file
modify rights separately from write permissions, or want permissions
inheritance or have resources accessible to more than one group at a time,
then you may have considerable difficulty trying to replicate that with
Samba.

A DSL router with a firewall, or IPCop which is nice and flexible.

Buy a DSL router/firewall that does wireless as well in that case. You can
do wireless with IPCop but it limits your choice of hardware pretty badly.
You can do wireless with Linux, but in your case I would not recommend it.

You'll need a DHCP server somewhere unless you're going to assign IP
addresses manually, but DHCP should be easy with a DSL router.
