Clicking is perfectly normal, if you look inside it is a series of springs pressing teeth into a gear. Clicks on wind and provides drag when pulling out line.
The type of fly determines the action. Poppers are common with bass, they are stripped with small jerky strips that pop just like their bigger counterparts. Streamers and Woolly Buggers are also effective and imitate small baitfish when stripped 6"-12" at a time, varying the length of the strip and pausing erratically produces a 'wounded' action great for reaction strikes. Dries are meant to be fished on top and usually represent insects and terrestrials, bass this time of year seem to like grasshopper imitations (hoppers). Some dries need floatant; a coating that helps them float otherwise they'll sink and not be effective.
As for Leader/Tippet:
I run 2x-4x leaders for bass. Usually in the 7-9ft range. Tippet I usually match to the leader and attach 2-3' to preserve the length and taper of the leader. Changing the tippet every session and the leader as necessary.
