I cast with my right hand, and keeping the rod in that hand, reel with my left. At least start out that way. You can always change later if you want to. Check to make sure your reel is set-up for left hand retrieve by pulling out some line and noticing if the drag engages going out or coming in. It should be on when the line is going out.
Most reels are convertible to right or left hand retrieve.
Now as you put the rod together, start with the eyes mis-aligned and twist the sections together. Not a straight pull, twist them about ninety degrees or so. When you are done make sure they are all nicely in line. This will seat them properly. Check the sections often to make sure they still have some paraffin, it can wear off over a season.
