Home network with Gigabit router BUT 10/100 port for internet sharing?

Hi.
I'm intending to network my house and I need a gigabit backbone for video streaming \ graphics editing and hopefully some grid computing (help is welcome on this subject as well).  I figure a gigabit switch with 8 ports is what I need. The problem starts here. I also want to share a broad band connection using my isp's supplied cable modem. So I figured I also need a router that has a regular 10/100 port for the Ethernet cable running up to the modem. Prob is The only combo routers with a built in switch I found for domestic use are 10/100 capable and enterprise gigabit routers use a gigabit routing port witch is very expensive and useless for me.

My first questions is weather I'll be forced to buy a gigabit switch and a separate 10/100 router (with a switch built in) – connecting the router to one of the switches ports and how do I assign ip addresses to the whole thing.

Second – are there affordable (250 + /- $) routers with a 10/100 port for internet sharing and a gigabit switch built in. I guess I'm not the only                    
               one with this kind of need… ?

I haven't seen any broadband routers with Gig ports - I don't think Gig NICs are common enough, yet, for the SOHO market.

Here is what I would do, for only $200!!! :)

Linksys
BEFSR11 Router ~ $50
http://www.linksys.com/products/product.asp?grid=34&scid=29&prid=142

EG008W 8 Port GigE Switch ~ $150.
http://www.linksys.com/products/product.asp?grid=35&scid=42&prid=529

This should pretty much work out of the box - you would connect the router to your broadband in the WAN port.  It would receive an external IP.  Then you would run a cross over cable - or if the switches are capable of auto MDI/MDIX or have a special port, you don't need it - over to the Gig Switch.  The Gig Switch is unmanaged.

Then, you plug your GigE equipment into the Gig and the non-Gig/hosts where you don't need to waste a GigE port on into the Router/Switch.

The Switches learn where other hosts are by themselves and build a forwarding table - traffic that is from a GigE device to another GigE device would stay in that switch - theoretically the only traffic which would go over to the Router would be bound for the Router (like DHCP requests) or bound for the Internet.

Thanks pseudocyber... one more thing though...
i checked out the gear at linksys and i couldent figure out the difference between the eg008w and the sd2005 -
as far as their spesifications go they are preety much the same.
how come only the eg008w user guide states "up to 20/200/2000 Mbps per port in full duplex mode" and the sd2005 user guide doesn't?
and by the way what does SOHO mean ?

SOHO is Small Office/Home Office.

Any port that can run full duplex can theoretically double it's speed - however, this is a marketing gimic.  What it means is you can run full speed in both directions at one time.  If you have a 100Mbps connection and you're doing a file transfer from A to B, you're NEVER going to go over the 100Mbps - because it's unidirectional.  There AREN'T any apps that need full speed in both directions at the same time.

I don't see a difference either in those two switches, besides port count and price.
