Thanks for this -- I've managed to solve this one now. Turns out the
username and password can be set through QgsDataSourceURI() by:

uri.setParam("username", "xx")
uri.setParam("password", "xx")

(rather then setUsername/setPassword).

The tilesize are set by the parameters maxWidth/maxHeight:

uri.setParam("maxWidth", "512")
uri.setParam("maxHeight", "512")

Cheers,
