To me the difference between Fly-fishing and fishing is kind of like the difference between bow-hunting and hunting. Both "sub-sports" are usually associated with a more"technical" aspectinvolved with "form" (casting and shooting) and their own complete world of equipment, language, and methods. Just like bow-hunting, imo, when success with a fly rod is acheived (usually doesn't take too long

) it is more rewarding.
Guss is rightin that you need to get hold of some good intro videos and books because there is a lot of information. Don't let all the info intimidate you as it doesn't take a doctorate in fly-fishing to be successful. It's just a lifelong learning process like other worthwhile outdoor pursuits. Try finding someone local who knowsa what they're doing to go fishing with--most people will really want to help you.
The rod you've shown will work for the short term but (just like anything else)if you become "hooked"--you'll want to upgrade and it will make a difference. One thing you might want to check into is putting the right line on that reel--it will make a world of difference right of the bat--if possible use "weight forward floating" line--in the right size. Ask any questions you want and I'm sure someone here can answer them.
I'd wait on the fly-tying part as that is a whole 'nother world to explore (one thing at a time

).
