Sounds like you got what you were looking for, I would take any money you got left over and invest it into a quality fly line that matches the rod properly. I prefer Rio lines but its all preference, Airflo is another good line company. Otherwise you'll likely become frustrated when trying to cast it with any accuracy, distance or wind.
A 5/6 wt will work awesome for all the belly boat lakes and some of the smaller to avg size salmon in the smaller rivers. If you get into a big sized fish on the river you will get into some trouble, Just point your rod straight at him and break him off so you don't lose your whole outfit.
Check out Spey rods if you got time to kill, they are awesome to fish rivers with. I think most people start with Single hand and move into Two hand at some point.
For Fly tying, I just went out and got the necessary components and started attending local fly tying nights and any classes put on by the local shops. YouTube is a great way to learn different patterns and techniques.
The hardest part about learning Fly fishing is leaving your gear tackle at home and learning how to catch the fish all over again.
