Hi there!
First thing you should do when you're all new at this visa-stuff is to read.
Then read again, bookmark, and then read it all once more.
There is so much information out there and once you start your search you'll come across many other things that you never thought would come in handy, but they do in the end.
I could answer your questions but I do urge you to find them yourself.
Start on this forum and work your way around.
Go see
www.cic.gc.caFind out what kind of visas there are and which one would suit you best.
I have no clue on what would be usefull for you to know, because I have no insight in the details of your situation.
Get used to finding your own way.
This may seem harsh but once you get to Canada, you will have to do the same thing.
Good luck on your knowledge-trip!
