Spanish computer talk

Hello, I'm here to ask for some Spanish help.  I'm going to be working in Costa Rica as a "website specialist", and while I speak Spanish okay, I've never had to deal with it in a computer context.  I'm not even sure what "website" is in castellano (oh hey, it's "sitio web"). Can anyone out there recommend a book or pamphlet or something that gives a decent rundown of Spanish equivalents of "double click" and such?  All I need is vocabulary, really.  I know, I should also try setting my computer to Spanish too, though it's a bastard typing the non-English letters on Windows and on an English keyboard.  Still, I'm definitely going to do that also.  I'm trawling through the Spanish wikipedia right now, but there must be something better out there (i.e., something comprehensive that I can read away from the computer).

While I'm at it, is there anything special about Costa Rican Spanish I should know about?  Something on the level of not using coger in the US?  I'm already aware of the differences between Spain and Latin America, I just want to know about the Costa Rican context.

Anyway, thanks for whatever help  anyone out there can provide.
