If you're trout fishing out west I would take the advice that a few have given here and get a 5 weight rod, not 4 weight. It's a better all around trout rod for western waters.
BTW, lots of decent vids on YT for casting basics. But like Lefty Kreigh points out, don't get too hung up on clock positions when learning to cast; it's learning to load and unload the rod. I believe he's got one or two vids on YT too. I'm sure you can get some basics from Bass Pro too in the way of a casting class.
I still use an old Sage 9/5 4-piece rod and an original Lamson 1.5 reel with WF line and a spare spool with a sinking tip line which I almost never use as I really only like fishing dries even though nymphing is usually more productive. Then again, I have no problem with ultra light spinning gear as I'm not a fly fishing nazi.
