Here's what I have:

 

A home network with a in Win 8.1 Laptop (wirelessly connected currently), a Win 7 desktop (wired) , an Ubuntu 12 media/backup server (wired), an old laser printer hard-wired via a print server, a wirelessly attached Roku unit and a wirelessy attached Blue-ray player.

These are connected to each other through an AT&T Uverse router and an old 10MB hub. Everything works fine.

 

Here's what I'd like to do:

 

Tie the laptop, desktop and Ubuntu server (and the print server) into a 10/100/1000 switch, which would then connect to the internet via the router. Can I get 100 megabit (or even gigabit) throughput computer-to-computer for data transfer if the NICs support the higest throughput?

If the switch is configured to support gigabit speeds, and the NICs support it, the only thing that would slow down your data speeds are your network cables. Make sure you are using at least Cat 5e Ethernet cables.

Actually cables never "slow" the transfer rate.  Due to auto negotiation of the nics, they determine what rate is set.

Older cables like Cat 4 can't handle gigabit data transfer rates, so using it would slow the transfer rate even if the NICs are gigabit. Cat 5 can handle those rates, but Cat 5e ensures better performance.

First you have to understand that speeds given are wire speeds, meaning on the wire they can move at that speed but it's going to slow down at the nics, your bus speed, your hard drives basically every thing that isn't the wire slows down data. But having said that, I doubt you'd see more than 4 - 5mbs throughput.
