Absolutely not. Your fingers will develop the hard skin necessary to play for extended periods. Just trust your body's ability to adapt and stop when it starts hurting. Using superglue or any other kind of protection only puts off the inevitable, and opens you up to other risks like accidentally supergluing your fingers together.
If you really can't cope then guitar is not for you.
No, that would only "protect" your strumming hand and would do nothing for the other one. Besides finger/fingernail strumming/plucking/slapping/etc are useful techniques in addition to picking.
