Welcome Keith
One of the first things you will quickly learn is that every angler (well, almost every angler) has different views on what tackle you should buy, where you should go to learn, who you should learn from etc etc.
The saying "time spent in reconnaissance is seldom wasted" is entirely appropriate to fly fishing, you will learn a huge amount from simply watching other anglers fish and asking questions. Although it's tough to do when you're keen to start I'd urge you to try and sit and watch some anglers fishing. To do that you need to go to the right places and, although I'm openly biased, I'd sugegst that if it's local to you Haddo is one of the best places you could start out.
Mike will see you right.
I'd suggest that once you've had some casting lessons a 9ft rod for a #6wt would probably be a good place to start out rod wise, there's plenty of suitable outfits available from shops and fisheries locally as well as online.
You could get 'proper' instruction which is very worthwhile and certainly money well spent. Again if you're local to the NE I'd be willing to give up some fishing time to take you through the basics although I'm not a qualified instructor I'm not entirely inexperienced. I'm sure other forum regulars would be more than willing to do likewise.
When you're starting out no question is too stupid so don't be afraid to ask any questions via the forum. You might get diverse answers but you will get advice
I hope that's of some help - but please just ask questions
