It should be. I don't think I've ever needed a cross-over cable for

The WAN port on the Linksys routes is the only port that allows an address
to be assigned. So if you want to assign an address to the Linksys, you
have to connect the WAN port to the dhcp server.

Assuming the Linux box is set up to forward traffic, yes that should work.

Yes, it's typically used to chain to another hub/switch. AFAIK, the only
difference between a regular port and an uplink port is that the uplink
port allows you to use a straight-through cable to uplink, as opposed to
requiring a cross-over cable.
Also, IIRC on Linksys switches, the uplink port is "shared" with the last
"regular" port. So you can only use one or the other, not both. You
said it's a 4 port switch. That should be 4 ports + 1 uplink. You could
only have 3 devices connected if your were also using the uplink
port...port 4 needs to be unused in that situation.

It would be easier to make suggestions if you gave a little more info on
what you're trying to accomplish. But, what you described is doable. But
I wonder if you even need the Linksys to do any routing at all. Seems to
me the Linux box, connected to a switch ( the Linksys via the uplink port
) could be good enough, and maybe eaiser.
