if so - in terms of classical EMF definitions where do the "field lines" go?

Out. The electric field is given by Coulomb's law.
[tex]\mathbf{E} = \frac{q}{4\pi\epsilon_0 r^2} \hat{r}[/tex]
[tex]\mathbf{E} = \frac{q}{4\pi\epsilon_0 r^2} \hat{r}[/tex]

Or in.
(depending on whether the charge is + or -, of course)

so charge DOES have energy? even in the absence for example a voltage gradient?

A charge creates its own potential field.
