A few questions to work/stay in Canada?

I am a US citizen and I have a job offer to work full time in Canada and going by CIC's online assessment, it looks like I qualify to be considered as a SKILLED WORKER applicant. I have the following questions to help me figure out what I would need to do to secure my stay in Canada:

1) What fees am I looking to pay? Medical? Any type of VISA fees? Police records?

2) Would I be able to stay with a friend in Canada while I work there or would I need my own residence?

3) I read that you need proof of financial status to show that you can support yourself in Canada, but If I have a job offer, as long as it covers the minimum needed, is that enough proof?

4) What would I have to do if I wanted to get another job in Canada in case I wanted to leave the job I was given?

Any other information I need to know or that can be of some help to me, would be much appreciated. If I can think of other questions, I'll just add them later. :P Thanks in advance. :)
