I was under the impression that the pass phrase encrypted the file and
that to make use of the private key I would have to supply my pass
phrase, so I thought the private key was useless without the pass
phrase.
Correct.
The 4096 bit just means that it would be pretty much impossible
with todays tech to brute force the pass phrase,
No, 4096 bit is the length of the key. Such a key is resistant to brute
force ("guessing it"). If someone has your key (encrypted with your
passphrase), the target of a brute force attack is obviously your
passphrase because it would reveal your key unencrypted.

Thanks for the key length explanation.
