Use $e^x$ when you're referring to a real number with a real exponent or a complex number.
Use $\exp$ when you're referring to the exponentiation function such as the exponentiation of a vector field.

Depends on the size of x. If you're just writing out something like a Boltzmann distribution or whatever, use the latter, but if it's anything complicated where you've got sums and fractions and shit in there go with the former.

Yes but different fields assume different values for the default base when none is specified in the log. In math it makes sense because you rarely use any other base except e.
