Rome wasn't initially a dictatorship; initially it was a senate. SPQR stands for the Senate and the People of Rome. The senate did remain in existance, though obviously the Emperor was the real power - at least in theory. There were certain cases when that wasn't true.
As for the senate, you're in part right. The senate was basically made up of the head of the important Roman houses, and though others could be removed (by censors) or given a position, it didn't mean they were entitled to speak. However, the senate elected members to their internal offices: The Plebian counsil for example voted for who would be the People's Tribune, or Tribunus Plebis.
Hmm, so George Lucas probably based Star Wars on ancient Rome, right? You know, the whole fall of republic, Palpatine secretly manipulating his way to the top (like Caesar), then, when he had enough military power (in this case, the clone troopers) forced his control over the galaxy by killing all of the Jedi. The Jedis were basically the protectors of the republic and had much influence over the republic, and by slaying the jedis (like how Caesar threatened the Senate) gained control of the Republic, and renamed it the Galactic Empire (Roman republic -> Roman Empire). But unlike history, democracy wins this war, as the Rebel alliance defeat the Empire, while the Roman Empire slowly crumbled under the pressures of nearby barbarian raids.
