Small business network setup

How would I configure the following?

Internet Connection via ethernet (cable modem (not static IP))
4 Port Router (Linksys wrt54g)
5 Port Switch
Dell Poweredge 1800 (MS Server 2003)
x4 MS XP Dell Machines
x2 Wireless MS Vista Laptops
x1 AIO Printer (epson cx9400fax)(connected via usb to PC)
x1 Network Laser Printer (Brother HL-4040cn)

What, I want to do is setup a business atmosphere in which I have business software installed on the server and to be able to run the programs on the PC's and Laptops?? Obviously I don't have enough ports on the switch or the router. Can I use them both? In which order do they go? Can I share the printer over a network attached only to one computer (epson printer)?

not sure how to answer your questions, I'm not even sure what the difference is. Is there a better one than the other?? As for connecting all the peripherals to the router, I can't do that because I have to hard connect at least 5-6 peripherals to a 4 port router. Is there a way I can use the switch as well? And also if you can explain the differance in what you were discussing about the networks. Thanks...

Don't forget to connect the Laser Printer to your network with ethernet cable to the switch or the router. You could install a wireless NIC in each desktop to leave the router and switch ports available. The other peripherals can be shared on the network from a desktop or laptop and do not have to be wired to the router.

I think it would be best to connect the cable modem to the router first and then to the 8 port switch from the router. Without the router connected you will not be able to share the internet between all computers, even the ones that are directly networked to the switch.
