Hi Tim,

Congratulations on getting married
Best wishes for the future.

As for next steps on your immigration journey, your wife now needs to submit her application for Further Leave to Remain using form FLR(M)
It's now known as 'Extension Of Stay In The UK as a Partner of a person present and settled in the UK'
This form also includes her application for her Biometric Residence Permit (BRP)

Here's a link to the form FLR(M)

Here's a link to the FLR(M) Guidance

BTW, FLR is not the same as settlement. It's further leave under immigration controls/restrictions
Technically settlement is ILR (Indefinite Leave to Remain) where most immigration restrictions are removed.

She can use her existing English Language test certificate provided:-

1. It's still valid and not expired
2. The test provider is still on the current list of UKBA approved tests.

Here's a link to the UKBA approved English Language test.

Have a read of the forms and links and ask any specific questions you need help with.

You have only 35 days before the fiancee visa validity expires. Means you really need to put a wiggle on and get the FLR(M) submitted presto presto.

DO NOT allow the fiancee visa to expire before UKBA is in receipt of the FLR(M) application AND also the payment.
