Hi,
Yes, you can get married not only after lodging send independent application but also after submitting medical and pcc. Remember, it should've been decided before receiving your grant letter.
As it's a change in circumstances then you'll have to send form 1022 and your wife's documents in order to include her in your application. Also, it's a good idea to include her as it'll not only save another fee but also refrain you from the complication of applying spouse visa for her.
Once you've received your visa grant usually you can't get married before validating your visa but in some cases you may be allowed to get married which all depends on your case officer.
As far as the delay is concerned, yes it'll put a delay in your application as your case will temp. be halted b-coz of the buttessment of your spouse but if you've not yet submitted your medical then it would not impact much and i would prefer you to go a head.
In my case i also got married in the last month after submitting my medical and pcc in May 2005 and just have submitted her docs to process her case as per instructions of my case officer.
Regards, M.Mateen.
