if u bring along your nets card when applying for water/elect/gas, giro is auto approved. usually u have to fill up a form and takes abt 2 months for processing. like what ryan says, if u dont need them, can apply later as there are chagres like sanitary fittings, disposal fees etc.
i didnt measure the bedroom but it looks long enough for me.

change of appointment, u can log into singpass at hdb website, click new flat tab, scroll down you will see change appointment.
for door opening, we did quite an elaborate 1 in my opinion, the whole ting lasted 2 hours..we didnt beleive it too...
one of my friends didnt do anything at all and just open the door, so it depends on your preference.
