TN and H1b with gap

I am Canadian and currently working under TN which will expire on Sept 7th.
I just got my H1B approval notice WITH the new I94 valid from oct 1. I think that means a automatic activation.
There is a 23-day gap between the 2 visas and I have several questions.

1. Is leaving the US(going back to Canada) on sep 7 the only solution?
because renew the TN will changed the departure number that same to the H1B's.

2. When leaving US before TN's expiration, will the new I94 be taken by US customs, resulting the annulation of H1B? because the H1B instructions say to attach new I94 to the original one if available.

3. When re-entering US, is H1 visa ok on oct.1st if it is already activated ( I94 came with H1B approvement)?


Thank you very much.
