No problem at all. Though I'm glad to help, you'll also find that in general, folks are very helpful around here- so don't necessarily hold a question back from the group... chances are, others want to ask the same question, and answering it in a forum makes it findable by others looking for info.
The only stupid question is the one you didn't ask, so they say..
One note about the library- it needs to be on a 5v 16Mhz arduino for the timing and voltages to be proper. That's the standard arduino, so you'll be fine. The library wouldn't work on a different freq or voltage out, most likely.
By the way, it's easy enough to use a laptop with an arduino.. just set a TV tray up or whatever and you can tinker and spend time at the same time. Wife likes her American Idol and all that, so you can sit and fiddle while blocking out the screeching cacophony.... and the TV too..
