The classic itinerary if you fly into San Jose is (in any order that works for you):
Monteverde/Santa Elena for the cloudforest. Be sure to do a nighttime guided walk. The guides will show you beautiful bird sleeping in trees, scorpions, tarantulas, etc., and you'd never be able to locate those things on your own.
Arenal for the hot springs, volcano, rafting, horseback riding, etc. Splurge on a nice hotel with its own hot springs.
Manuel Antonio for the fantastic nature and the beaches. Definitely get the guide again (only use the official national park rangers) for the walk to the national park beaches. They'll help you spot and photograph wildlife that you'd never ever see if they didn't locate it for you.
If you have more time you could hit the west coast beaches and if you're more adventurous, the Caribbean beaches.
Enjoy! We loved very minute of it.
If you want to see unspoiled wilderness and wildlife, go to the Osa Peninsula. If you want to go ziplining, rafting, visit herpetariums, etc. this is a good itinerary.
