The AucTeX package provides a complete emacs environment for editing LATEX documents.
C-c = runs the reftex command reftex-toc which will split the current Emacs window to show two buffers, the top buffer showing the table of contents of the whole document, allowing quick navigation around the document.
The preview-latex package will provide a preview of graphics and mathematics inside the emacs buffer where the LATEX file is being edited.
