No. Once completed, you're completed. You can destroy the FSM.

There is no ACK for non-INVITE.

The spec says that the server should cache the final response for 10*T2.
THis is in section 14.3.1.

I think I answered this in a previous email.

non-INVITE: till it transmits a total of seven requests. From 14.3.1:

Retransmissions cease when the client has sent a total of eleven packets, or
receives a definitive response.

INVITE: if it receives a 1xx, its a client implementation choice. If it
never gets a 1xx, its until it sends seven requests. That seems pretty clear
from figure 10.

32s. Also very clear from Figure 11.
