"Should have" (often contracted to should've) sounds exactly like "should of" when spoken quickly, but "of" is a preposition, not a verb! We always use the auxiliary verb "have" after a modal like "should" or "could".
"Supposed to" requires the "d" at the end because it acts as an adjective here (from a passive verb form). Because the "d" blends into the "t" in "to" when speaking, people often mistakenly write "suppose to".
