Welcome to the forum,
For basic panfish and bass you'll use a floating line almost the entire time.
As flydoc said, stick to short leaders.... poppers are a fun way to get started especially in sizes small enough for panfish (size 8 or smaller). This is usually productive from April to October. If youre targeting bass specifically larger poppers and fish imitators (streamers) work well, with poppers being most productive at dawn and dusk. A great time to flyfish is right after ice out and the crappie start moving shallow. The best method is to use a small minnow imitation stripped with a jerky retrieve...
have fun and great fishing
