There's actually another Azula/Caesar parallel - obsession with hair and general appearance. In his youth Caesar was besotted with his personal appearance - his hair had to be perfect, his clothes had to be the latest fashion, and he was so particular about his hygiene that when he was appointed as the governor of Spain, his first act as governor was to order the construction of a massive bathing complex. As he grew older and was appalled to find himself going bald he had a special act passed in the Senate allowing him to wear a massive golden crown in recognition of his conquests - just so that he could cover up / distract people from his baldness.
And you're right, his assassination also parallels Azula - after years of beating anyone and everyone who dared to challenge him head on, he was ultimately brought down by his own friends. The actual assassination was close too - when the senators first started attacking him, Caesar fought back ferociously - clubbing several of the assassins unconscious with a scepter and managing to stab several others with their own knives, all the while roaring about how he was going to make them pay for their treachery (similar to the way Azula was about to kill Mai). But when Caesar saw Brutus in the crowd, all the fight went out of him. He could not believe that someone as close to him as Brutus could betary him. Contrary to the Shakespeare play, Caesar's last lines to Brutus were actually in Greek - translating as "You too, my son?". Brutus was actually the son of one of Caesar's mistresses, and while it was never confirmed that Caesar was his father, Caesar apparently saw him as the son he had never had. The reason the line was changed in Shakepeare's play was because he did not want to include this sub-plot, feeling that it would complicate the storyline. Having uttered his final words, Caesar wrapped his toga around his head so that he did not have to look at the faces of the people who had betrayed him ("Take them somewhere where I'll never have to see their faces again!"), and calmly waited for death.
Shi Huang Di is obviously the best parallel for Azula as we saw her in the show. Julius Caesar is a parallel of what Azula probably would have been like (or may yet become like) if she had not been a villain; but had instead devoted herself to good causes, albeit in a ruthless manner.
