Regarding uncovering the fwd fuel pumps - are you sure this isn't more to avoid damaging the pumps?
More likely to avoid damaging company property while my

Don't always be sure about Sharjah taking you, at least not immediately. I came back to DXB a year or 2 ago and had unforecast fog. KLM 74F behind me was told to reduce speed and take vectors. When he indicated he didn't have enough fuel and wanted to divert to SRJ, the answer was.....
"I'll see if they will accept you".
Personally, I will add some extra to the contingency to ensure I have the 20 mins holding.
