Msn/Outlook/Microsoft e-mail and how do I transfer

I have msn dial up and an .msn account for my e-mails.  Everything is now showing up as outlook/microsoft.  If I cancel my msn dial up will my .msn/outlook/Microsoft account disappear?   How do I transfer my contacts and emails to either gmail or yahoo.  I don't know where exactly my e-mail is and I'm not thrilled at all with all of this msn/outlook/Microsoft confusion not really knowing where my account is.
