First, I think that you should read through Brandon Turner's epic House Hacking Post here:

I'm using this strategy myself and think that it offers new investors one of the best ways to dip their toes in Real Estate while giving you the ultimate in exit strategies - you can just live in the place a little longer than planned if things work out sub-optimally!
A couple of notes on your specific points:
0% Down may be very difficult without getting super creative. The advantage to house hacking is that you can use owner-occupier financing like an FHA loan. For single families, that can be as low as 3.5%. For a small multifamily (2-4 plex), you will likely need to put down at least 5% or a little over $16,000 in your case for the $325K triplex.
You'll also be paying ALL of the expenses. Tenants pay nothing for that in most cases. You are a landlord after all. The good news is that between the two other sides' rent, you should be able to cover all or most of your mortgage, making your house hack a huge cashflow win over renting or buying a single family.
