The difference between fly fishing and baitcasting or spinning tackle is you cast the one, not the lure.
Your rod needs to be long enough to cast the line with whatever fly or popper you are using. The bass flies and poppers have more air resistance than most trout flies so you need heavier line and that requires longer rods. The reel is simply a line storage stowage when fly fishing, you use your hands most hold the line and work the fly most of the time when fishing. When you hook a fish you still use your hands on the line and the rod to control the fish. Since bass don't make long power runs you rarely use a reel during the fight.
As everyone has noted put the money into the rod and line, a basic fly reel that holds the line is all you need, even with fish like carp.
Fenwick makes excellent fly rods at a reasonable price point; Fish Eagle 9', 8 W, $99. Okuma Cascade reel $25, SA WF-8-F line $45, Dacron backing $5, taper leader $5, total about $180, plus tax.
