My Girlfriend and I recently imported a '94 Jeep Grand Cherokee from the states. I'll try my best to recall what had to be done.
1) DRL Module - as the the states don't require daytime running lights you'll have to install them. It's a simple module that you may be able to install yourself, if you're handy. I'm not, so I didn't.
2) Go to your nearest toyota dealer and have them print up the list of Service Bulletins for the vehicle. This document will indicate if they have all been done. And is required for step 4.
3) You have to go to the border to have a form filled out. (i can't recall which form, as it was my girlfriend who did this, but its a good bet that it's related to vehicle importation).
4) Then you have to go to a shop that will ok the vehicle and allow it to be imported. There aren't many shops that do it. For instance, i'm in Ottawa and had to drive ~45 min out of town to a shop in the middle of nowhere. Bizarre. Apparently some Canadian Tires will do this. But do you really want to bring your car to Canadian Tire?
All of this is above the E-test (if required) and certification.
We didn't have to make any adjustments to the spedometer as there were km/hr markings as well as mph.
