FiOS/networking question

[jsf]

Hey folks,

I have FiOS coming to the house.. it is brought into the basement of
my house... I've had it for over a year now and what I did was this:

I completely bypassed the D-Link non-wifi router they supplied and
instead took the Cat5E cable coming out of the FiOS box in my basement
and plugged that into a RJ45 jack in my basement wall.  I have cat5E
running from that jack up to a jack inside a cabinet in my kitchen.  I
then use a short length of Cat5E cable running from that jack to the
uplink jack on my Linksys WRT54G Wifi router which is stuck to the
wall in my hallway on the other side of that kitchen cabinet.

So, the Linksys connects to Verizon over PPPoE and our various laptops
in the house use their wifi cards to pickup DHCP addresses from the
Linksys.

I maintain a DSL line from Speakeasy with a single static IP address.
I have one linux box conencted to that DSL modem and run my apache,
Postfix, etc. off of that for all of the domains I own.

This has been fine for as long as my employer has been willing to pick
up the $52.13 for the Speakeasy account.

I will likely be changing employers soon and the new employer is
unlikely to be willing to pick up this expense.

On Friday I signed up for a $20/month MediaTemple GridServer acct.  I
have pointed DNS for most of my domains to the Media Temple setup and
moved all of the websites there.. it was all pretty painless.

Before I retire my Speakeasy DSL I am trying to figure out how to do
the following:

1) connect the FiOS uplink to the D-Link non-wifi router

2) plug the two computers I have into the basement directly into the
D-Link router and have them connect either via DHCP or PPoE to the
FiOS account. (one of them is currently plugged into the Speakeasy DSL
and the other picks up a DHCP addy via the Linksys Wifi).

3) get the Linksys WRT54G connected to the D-Link via my wiring in the
walls and somehow have IT get assigned an address and then have our
laptops pick up an address via DHCP (I guess) from the WRT54G.

I'm not sure what configuration might be needed on the D-Link to make
this work, nor how to do the configuration.

I'm also not sure how to tell a SuSE 9 box how to pick up an addy via PPPoE.

Any assistance with figuring out how to get to the new config. so
everything works.. the two workstations downstairs and the WiFI router
upstairs on JUST the FiOS would be greatly appreciated!

TIA,

Joshua
