A Tough one...VBA coding

This is a tough one, I hope some gurus can help me. I have coding that does number 1&2, but I can't figure out how to keep that and do 3 and 4.


I'm going to attach the document and then explain what I'm trying to have happen.

1) worksheet named current: when I change the status in status column to Booked - the entire row will be deleted and moved to the Booked worksheet.
2) worksheet named current: when I change the status in the status column to DNMQ - the entire row will be deleted and moved to the DNMQ worksheet.
3)worksheet named current: when I change the status in the status column to Application, I want todays date to appear in the App Date column (G). I don't want this date to change each time its updated or saved though. A static date if you will. Also, if I change from Approved to closing I dont want the date to change in the column G. Once its there I don't need it to change for tracking purposes.
4) Finally, when there is a change in columns A-F I want another static date to appear in column J. This date wont change until their is any change in columns A-F.

Any help or ideas would be so appreciated.
