If you want to read about the SLINGERS -- and why wouldn't you?! -- these are the comics you'd probably want to read:
1) The Identity Crisis Spider-Man Crossover -- the origins of the Slingers costumes (though not in-story)
2) Slingers 1-12 -- the definitive Slingers storyline
3) Civil War #6 / Avengers: the Initiative / Fear Itself: Youth in Revolt -- lots of focus on Prodigy throughout this era of comics
4) Avengers Academy -- Ricochet is a background character but does get some screentime, including a reunion with Prodigy
5) Ben Reilly: the Scarlet Spider / Spider-Man: Beyond -- the Slingers become embroiled in the shenanigans of Ben Reilly
Other than a few minor appearances, reading these issues would provide you with an almost complete history of the Slingers!
