Setup a local network (2 win98 PC's)

I have two freshly installed windows 98se PC's connected to different
ports of a linksys wired router and then to a DSL modem. Both PC's
are enjoying concurrent access to the internet, both have "client for
microsoft networks" installed and both have selected "microsoft family
logon" as their primary network logon. They have different computer
names, but both have the same workgroup name ("HOME").

Now I would like to take the next step in setting up a local network
so that these two windows 98se PC's can access each others hard drives
and printers.

Please advise me as to what I do first, and I hope there are step-by-
step instructions somewhere that can guide me through the whole
process. My goal is to be able to use windows explorer (NOT internet
explorer) and have new drive letters show up that are mapped to the
other PC's hard drives.

Any help would be greatly appreciated. I didn't make any non-
recommended selections during windows 98se installation, so, I suppose
I don't have any firewalls or anything you wouldn't get during the
recommended windows 98se installation..

Help.
