You can't use a variable as a query param if the same variable is a
path variable or constant in the relevant route. All Pylons routes
define 'action', and a few define 'id'. It shouldn't matter if you use
keyword args or **myReqParams because the same variable can't overlap
between the two.
The solution is to use ``webhelpers.util.update_params`` to add the
query parameters:
h.update_params(url(controller="controlpanel", action="formgen"),
id=1, action="edit")
Also, 'url' is a standard template variable in Pylons 1, so you don't
need h.url in templates.

I don't understand the question. If the route is defined with a
trailing slash, it will be generated with one.
>>> mapper.connect("abc", "/abc/")
>>> url("abc")
'/abc/'
>>> url("/lala/", id=1)
'/lala/?id=1'
