Theming with CiviCRM and Drupal, php variables, basics

I've installed CiviCRM with my drupal installation, and I am creating a custom theme. What is a good resource for utilizing CiviCRM elements in the theme?

I need to give/pull these things to/from CiviCRM:

Registration elements, Basic CiviCRM variables, and Profile elements...

Sorry if it seems like a newbie question to some of you, but CiviCRM.org seems like it's t开发者_JS百科oo full of filler language...

Thanks

What you're looking for is the CiviCRM API. Try this page: http://wiki.civicrm.org/confluence/display/CRMDOC40/CiviCRM+Public+APIs EDIT: Updated link

I've never used CiviCRM, but a good resource for finding how to retrieve data from CMS modules in general is to look at the code for the module/extension/plugin itself. It will often be retrieving information the same way you can for your template.
