Creating a new entry in a specific section
The EntryModel you have has a sectionId property you can set.  i.e.

 $entry = new EntryModel();
 $entry-&gt;sectionId = 1;
 $saveIt = craft()-&gt;entries-&gt;saveEntry($entry);


Note that there are other properties you'll need to set for it to pass validation.  So, if $saveIt is false after calling saveEntry($entry), then call $entry-&gt;getErrors() to get an array of validation errors to fix.
