My package calcE does this automatically when both endpoints are
multiples of Pi (incl zero), and a simple option (UsePi->{True,False})
does it otherwise.
For example,
PlotE[Sin[x],{0,2Pi}]
will place tick marks at multiples of Pi.
Check out

for an example and further information.

Not really. For an arbitrary function this is no simple matter and I
don't have any sudden inspirations.
The period of Trig(c x) is (2pi)/c, where Trig is any trigonometric
function. This covers >=95% of the cases that come up.
