What kind of shortcuts? Most LaTeX symbols will be replaced with their unicode counterpart, eg. \theta will become θ inline, once you toggle `entitiespretty' with C-c C-x \. Likewise for superscript and index, it changes as you type.
My equation blocks are created with M-o M-s which centers the current line in the buffer (when in fill-mode), so no need for C-c C-e equation.
