Comparing the government of Italy to the EMPIRE is ludicrous. The Empire's power is on a whole different level than the government than Italy. The Empire would CRUSH the Hutts in no time at all.

Well, tehre's always the question of gain. You can see in ESB the Empire uses the services of bounty hunters. Obviously they provide for some need the Empire cannot do themselves. It's not strange to think the Hutts' tentacles spread far in outer rim territories, where the Empire is less present, that knowing the Hutts control these area's, makes everything rather under control. All you have to talk to is the Hutts, and all you have to leave alone are the Hutts.
The Hutts aren't a threat, but they're a good way to keep the natural seedy underbelly of the population in check without the Empire putting in the effort. Feckin' things up just wouldn't be worth it.
And in the year that passed between ESB and ROTJ, without bringing in the dreaded EU, how would Vader have gained Luke's rescue-schedule?

I think Vader knew that Luke was going to rescue him. Maybe Vader wanted Luke to succeed so his powers could expand by facing Jabba and make him more powerful so he can use him vs the emperor.
in Shadows of the Empire, Vader is informed that Luke is captured by bounty hunters. Vader goes to retrieve Luke, but upon arrival, he finds that Luke escaped, all the while "blocking blaster bolts with his lightsaber.".....Vader is angry that Luke escaped, but is pleased that Luke has taken it to the next level.
