doesn't matter what passport you have, if you are married, you can apply for a dependent visa for your wife.
as for PR, i LOVE the freedom that it allows me. i can change jobs as i like, start my own businesses and not have to worry about visa status. i've never had a problem finding a job that can/will sponsor me, but i much prefer being my own boss. without the resources to apply for any of the other "schemes", PR is FANTASTIC for me.
