Extraction and bridge question

I have treatment planned an extraction and 4 unit bridge for a patient. The teeth around the tooth to be extracted are crowned currently.

I was wondering would it be best to do the extraction. Section the crowns and place the patient in a temporary crown right away. So that he has all his teeth. Or just to extract the tooth and wait.

Also how long should I wait. To do the full bridge. I was taught 6 weeks but I know this Patient is going to be calling my front desk every second or third day. Link to tooth:
