May be just a bit early, but in the summer beetles and ants are good choices.
Standard nymphs like hares ear will work as will streamers like Wooly Buggers.
Soft hackles would be another choice.
Under a bubble, chironomid pupa or balanced leeches will work. Kids will like watching the bubble dive when a fish hits.

As far as beginner outfits go, I'd look at Redington, Echo or TFO.
They all offer outfits that won't break the bank.

Have fun.
