The basic form is "traer", that's right. TRAER means TO BRING For example the Present is: yo traigo, tú traes, él trae, nosotros traemos, vosotros traéis, ellos traen. The sentence "Bring us something, please" is using the imperative. Imperativo: trae (tú), traiga (él, usted), traigamos (nosotros), traed (vosotros), traigan (ellos, ustedes) So it could be translated as: "Tráiganos algo, por favor" (Polite way, usted) "Tráenos algo, por favor" (Informal way) "Bring me something": "Tráeme algo" (with friends and used most of the time in Spain) or "Tráigame algo" (usted, very polite /formal) "Bring her something": "Tráele algo" (informal) or "Tráigale algo" (polite)

The infinitive is as you said - traer. Conjugation of traer can be found here (http://www.spanishdict.com/translate/traer) or anywhere else. Traíganos - bring us, when you talk formal (usted). Tráenos - bring us, when you talk informal (tú). The verb part changes according to the person you are speaking to - usted o tú. The pronoun part - nos, me, te, le etc. defines a person who "receives" the action - bring me, bring her etc. Bring it to me - tráigamelo (usted). Bring it to me - tráemelo (tú).
