No.

You don't even have to have heard of "e".

No differentiation unless its powers.

C3 does all the other differentiation (except for parametrics and implicit).

C4 does implicit, parametrics and a whole lot of integration.
3. e^x isnt hard to differentiate anyway... e^x -> e^x :P

Yeah, but there is no need for any unecessary information to be stored away in your brain. Stuff it full of stuff you need to know.
5. yeah all you need to know for differentiating e^x (and as said above, it's NOT C2), if you have just e^x, it differentiates to the same, and if you have e^2x it differentiates to 2e^2x and e^4x to 4e^4x and so on.
