Sounds like you have sts on holders for the right and left fronts. I would follow the instructions as given, knit across the 29sts for the R front,then take the needle with the sts in your left hand and cable or knit cast on 44sts, switch the needle back to the right hand and knit the 29sts of the L front. There are probably directions later for sttaching the hood to the back of the coat.
There are videos under the Free Videos tab at the top of the page, Cast Ons if you need them.
If I understand the orientation of the sts correctly, it may be better to do a 3needle bind off to seam the two edges of the hood at the top rather than bind off. It's a darling coat! http://www.ravelry.com/patterns/library/duffle-coat
