If the card is able, then a cable connection, and a dialogue set up window or two, and you're in business. It is really nice to have the additional screen real estate to work with. It has been a while since I set mine up, and I tend to leave it be once it is the way I like it, but I'll look mine over again if any of you want a run through. I'm sure there are others here who are more computer savvy than I, but it isn't all that difficult usually.
A nice option is a laptop with a permanent docking station of sorts. You have two monitors, keyboard and mouse at home (the permanent monitor is usually nicer than the laptop screen), but you can disengage the laptop at will and take it with you.
Or a 'serious' desktop workstation with multiple monitors in a more permanent arrangement can boost productivity, especially with software that uses a number of windows open at once.
BvB covered all the basics, if you computer is less than around 2 years old you can probably plug a second monitor in and it will work, if not you would have to go and buy a uprated Graphics card that can handle multiple monitors.
The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.
