Answer 1

Yes, all params will be strings.

This is extracted from the expressjs route.js:

var val = 'string' == typeof m[i]
  ? decodeURIComponent(m[i])
  : m[i];

So the val will always be a string, since the result of decodeURIComponent is always a string, while m is the result of a RegExp.exec() which returns an array of matched strings, so it's also safe to assume that m[i] will be a string.
