It would have helped if you had had something specific in mind!
¿ los tatuajes? (tattoos?)
démelos (give them to me)
no me los dé (do not/don't give them to me)
(First thing I thought of!)

Since you are asking at this point, you have probably not met the irregulars yet. (Any verb with the "yo" form irregular, such as decir = digo = di (tú) & no digas)
As for object pronouns with commands. With affirmative commands, they are attached to the verb (as in the first example I gave you) with accent marks on the vowel you want to hear) and in the negative they take the usual position, in front of the conjugated verb.
Direct-Object Pronouns: me, te, lo, la, nos, os, los, las
Indirect-Object Pronouns: me, te, le, nos, os, les (*le or les followed by lo, la, los, OR las, is changed to "se."
Indirect-Object Pronoun precedes Direct-Object Pronoun.
