I'm not sure I follow you here, but IIUC then yes that's your best
option.
However, as I said: I'm really not sure I understood how your code is
articulated: where are you calling History.getToken()? where are you
calling History.newItem() ? where are you willing the Location.replace
() to take place?
Is your "best option" something like at the end of your "screen set-up
routine"?
if (History.getToken().length() > 0 && !tokens.home_token().equals
(tokenToSetUp)) {
History.newItem(tokenToSetUp, false);
} // else: we're on the "blank" token and asked to display the home,
page, do nothing.
If yes, then I'd say it's OK, or you could refactor things to only
"react" to onHistoryChange and make your onModuleLoad call
History.fireCurrentHistoryState() and your menu system call
History.newItem() instead of calling the "screen set-up routine"
directly.
But a few lines of code showing how your "navigation" is articulated
would help...
