amsmath conflicts with wasysym (redefines \iint), so you have to
redefine your headers to omit wasysym or include amsmath *first*: for
some reason, if you \usepackage{amsmath} *before* you
\usepackage{wasysym}, the error does not arise -- presumably, amsmath
assumes that \iint is not defined beforehand, whereas wasysym does not
make that assumption.

It would depend on whether you use the dvipng mechanism or the mathjax mechanism
for math visualization. In the first case, amsmath is automatically included by
org mode (before wasysym, so no problems). In the second case, I wouldn't be able
to tell you: I've had problems with mathjax that I've wanted to investigate for ages
and never had the time - one of these centuries I'll get around to it...
