Permanent card

Hello Please help,

I landed in Canada on 2nd Nov 2010 and got my SSN. I came back within 1 week to UK. I have a friend in Canada who is a canadian citizen.
I want to apply for PR card in Feb 2012 by staying outside Canada. My plan is fill the respective forms.
I have taken a Canadian PO Box in joint acct. with my friend.
I am going to take phone service and ask them to send my bills to PO Box.
I have Confirmation of Residence.
My Question is If I am staying outside Canada can I send all my completed forms to friend and he applies for PR card.
According to what I read If you are freshly landed in canada then it takes max 45 days for PR card but if you go out of Canada and then comeback again then it takes 135days to get PR card. I don´t want to wait sitting idle w/o work for 135 days after arriving in Canada.

In PR application form they have asked about address should I put all my UK addresses and one last address of friend´s showing them as if i stay with him and after arriving in canada I can show them ph bills which will arrive in my PO box.
The fear I have is I don´t have any proof of tenancy in canada.
2) When this is going on I want to apply for canadian Travel document in UK. Can I apply for TD and PR card at the same time.
How long will it take for my TD to come?

If everything I said above is ok then my PR card will arrive at the local office and I have to collect it within 180 days after an Officer
informs me about it.

Any help will be appreciated.
