For this purpose you need to call IType.getFlags() method and check for Modifiers.AccModule flag. It it is set then
IType is a module. If not set then it is class.

To find types you should use SearchEngine.searchAllTypeNames() methods.

Example of using it to search types by name:

IProject prj = myProject;
IScriptProject project = DLTKCore.create(prj);
String patternString = "myClass*";

// Requestor will accept matches
TypeNameMatchRequestor requestor = myRequestor;
IDLTKSearchScope scope = SearchEngine.createSearchScope(project);
try {
	SearchEngine engine = new SearchEngine();
	engine.searchAllTypeNames(null, 0, patternString.toCharArray(),
				SearchPattern.R_EXACT_MATCH | SearchPattern.R_PATTERN_MATCH,
				IDLTKSearchConstants.TYPE, scope, requestor,
				IDLTKSearchConstants.WAIT_UNTIL_READY_TO_SEARCH, null);
} catch (CoreException e) {
	e.printStackTrace();
}


For more information about search you could look at SearchTests class from org.eclipse.dltk.tcl.core.tests plugin.
