The 2nd thing is to consider being a contributor, vs just a taker - and support the board by joining as a paid VIP member. You also are entitled to many discounts

as a member. Guys will help you regardless, but supporting the board is always a great way to start, and separates you from the pack.
3rd thing I'll do is echo Jazz' suggestion as to where to start, and Oranges advice piece is a good place.
Use the Search feature (although I'll be the 1st to say on this board its far from perfect) and see what/where that gets you - for example, there is famous volcano, called Arenal - type that into the search feature, and a lot will <likely> pop up. There is probably no truly new question, but guys will be happier to help you if you look like you have a clue when you ask.
The way to get answers is to do a little basic research, a lot of reading, and ask more pointed questions that show you too the time to help yourself as opposed to the average newbi dummy who basically says let me prove how little research I did by the questions I ask, and how truly dopey I really am - help yourself a little!
None of the above is a shot at you personally, just some observations based on your post that can help you out when you get to questions about what you read.
I could make your life so easy by saying:
a) stay at the Sportsmans Lodge - but not during Christmas or Easter week
b) contact via PM Bangbang57 and ask him if he will do a walk with you early in your trip, like 1st or 2nd day and show you around
c) go to Zona II and Scores, gringo oriented MP's and hang out for a while; talk with other guys
d) realize the Delrey may be the best known option, but is not the "best" option
e) don't over plan, go more with the flow, and realize if phucking is your main goal there is no better place in all CR to do it than San Jose
Just some food for thought - good luck
