I'm in the same boat, except that I was only in halls for one year. It's quite a change! Some of this advice might seem really obvious, so please don't feel insulted.

Seeing as you mentioned bringing a bed, I'm assuming it's unfurnished, so I second the suggestion of a trip to IKEA. If you have any items from home that you can bring with you, that would save money and also make it seem more familiar. A kettle is good for if the hot water stops working (it should be your landlord's responsibility to pay for repairs if it does, assuming your rights as a tenant in Canada are similar to those here) - as well as for making cups of tea.

As for setting up bills, it's probably best if you get the phone done first - that way once you get the line connected you can arrange other bills using it instead of your mobile, and it should be cheaper. Have your bank details and address to hand, as well as meter readings for gas and electricity (ask your landlord where the meters are if necessary), and be prepared to spend a lot of time on hold! If your phone number gets changed when you set it up, make sure to tell your landlord of the new one. A spreadsheet is a good way to keep track of your bills - I use Google Docs. Internet might take a bit of time to set up, though - mine still isn't yet, I have to wait until Tuesday! If your university library gives free internet access, that could be useful - otherwise, might be an idea to have a look for internet cafes nearby.

If you notice anything that needs repaired, tell your landlord as soon as possible - it should be the landlord's responsibility to pay for repairs (check the lease first, though), but he needs to know first! Exceptions would be for emergencies like leaking pipes, though.

As for dealing with neighbours, be friendly to them when you see them and let them know if you're going to have a party! If you don't make too much noise at night there shouldn't be any problems. Did you get a chance to talk to the previous tenants? They could tell you about the neighbours - if not, the landlord might be able to.

Hope some of this is useful, and have fun in your new place!
