Answer 1

Take a look at com.liferay.portlet.documentlibrary.service.DLFileEntryServiceUtil

Specifically

com.liferay.portlet.documentlibrary.service.DLFileEntryServiceUtil.getFileEntry(long groupId, long folderId, java.lang.String name)

You will get DLFileEntry so

DLFileEntry dlfe = com.liferay.portlet.documentlibrary.service.DLFileEntryServiceUtil.getFileEntry(my-group-id, folder-id, name);
dlfe.getReadCount();

will get you what you want.
