I am using regular size 9 knitting needles, not the straight round ones.

I am planning on using a bulky yarn sized 6, but i dont think this detail matters.

No one is going to be able to explain to you how to knit a sweater here. First thing you need to do is learn how to knit and read patterns. Go to http://www.knittinghelp.com to get started. It’s free and a great site for beginners.
