2.) What should I use for keywords for my new icon?
For #1, I've always been a big fan of the gimmicky "character" flavors that were introduced in the early 1990's. Kool-Aid doesn't get much better than Purplesaurus Rex, Sharkleberry Fin, Great Bluedini, or Incrediberry. Since they're no longer available, I guess cherry or berry blue are my favorite of the flavors that are currently available.
