When I have amc get subs can I specify the naming convention?

i.e. "subFormat={n} ({y}){'.'+lang}"

Yes, movieFormat and seriesFormat is applied to video files and subtitle files.

Can someone give me a hand with my language adding format?

{'.'+lang}
{".$lang"}

Both give "ScriptException: SyntaxError: unexpected token: ."

{\".$lang\"}
.{lang} - just a sanity check

Both worked but added an extra . before the extension for non sub files.

Do you know how " ' $ etc work in the *nix shell? You're doing it wrong, and thus not passing what you think you're passing. You need to escape special characters correctly.
