Canards and catsuits
If you need to make wings and tails distinctive, play around with number and positioning and stuff. For example, Morrigan from Deathstalkers has batlike wings near her center of gravity at her waist and smaller ones on her head. Princess Kurama from Urusei Yatsura has just the head-wings. She uses them mostly for expression, but she probably can use them for balance or cooling, too. Mink from Dragon Half has "retractable" wings via a limited shape-changing ability.
As for tails, if one tail is good, more tails are better! Load 'em on! Also check out Jone in ClanBob. She has a "prehensile" tail with a vaguely birdlike taloned claw on the end.
