The thing is, in 3rd Ed. they don't use kits as such - instead they allow you to tailor your character to exactly what you want. A kit is basically just a template of collected skills, abilities and feats which create a specific character stereotype.
For example, if you chose ranger as a class, chose Point Blank Shot and Rapid Shot, and Weapon Focus: Longbow you'd have a starting point for an archer. The only things missing are the kit special abilities and I'm guessing this is what you're missing.
