You are talking about a crossover LAN connection with a single LAN cable. More modern LAN adapters do the cross-over internally so that you don't have to get a specially crimped "cross-over" cable. I've personally had more success with static IP addresses on both machines rather than DHCP when doing this. Also tend to your advanced sharing settings in windows Vista or later, so that sharing over the network is set to "allowed".
W.r.t. to copy speed:
100GB is realtively small and should copy over the LAN cable within half an hour if you have gigabit LAN on BOTH machines. If both your laptop and desktop have gigabit network adapters, then you will typically get 240 - 480 Mbps. I know this is not close to the theoretical speeds of gigabit LAN, but these are typical speeds for copying over gigabit LAN with Windows OS.
A more troublesome route for a beginner would be to remove the HDD from the laptop and plug it into the PC, but you might run into some file ownership issues afterwards, especially if you are running windows 7 or 8 from within a different Microsoft account than the one on the laptop.
Hence I advise using the LAN cable method.
Both of my machines contain a Gigabit network adapter, so LAN would be the fastest yes?
You could take the hard drive platters out and stick them in your DVD drive.
No, but LAN ethernet transfer would be the fastest and easiest way to transfer the files. Don't worry about crossover unless you know how to configure it. Just use a gigabit router or such and transfer them that way. By the time you've swapped the HD twice, you'll likely be done. Plus swapping disks can possibly introduce problems.
If you have usb 3.0 and an external Sata to Usb connector, you could do it that way, (if the drive has been laying around)

you can find cheaper ones too. They're nice to have around
