Happy Holidays and the like, Kiz. If you choose to close the engine bleeds in your descent for landing for performance, to remain pressurized use the APU to pressurize the aircraft. And then set the pressurization as per normal. (make sure the crossbleed is open)

Flaps 45 was no big deal, as EMB-120IP stated. I flew with and taught both captains and co-pilots for many years on doing Flaps 45 ILS'/landings. It just takes practice and knowledge of the effects on the aircraft, and viola.....Touchdown, some smooth, some not so much, but all in all good none the less.. Hope that helps some. Enjoy the rest of your weekend. Take care and KEEP SMILING!!
