This is my understanding
1) As soon as you take the oath and receive your certificate of Canadian citizenship you will be accepted into Canada at a port of entry regardless of whether you have a passport or not, you just need to be able to prove that you are in fact a citizen. (The certificate will likely suffice) -- however, you will also need to have some sort of valid identification to prove it is in fact your name on the certificate.
2) It is extremely unlikely that you will be allowed onto a commercial vehicle (Plane, bus etc) of any kind without a valid Canadian Passport. But you would be able to drive.
3) In order to enter another country, USA in this case, you would have to have a valid passport and if required a visa. If you come from a country that does NOT allow dual citizenship (and I believe India is one) then your passport immediately becomes invalid as soon as you accept Canadian Citizenship. I would think, that when the official updates your information in the CIC system it would propagate internationally (I cannot be certain of this, but I think it's a reasonable assumption). You would then not be able to travel into the USA as your original passport would become invalid.
4) If you hold dual citizenship, then you would be allowed entry into the USA on your original countries passport, and you would be allowed to reenter Canada with the certificate; again, IF you could get to a port of entry.
