facelift bulbs are 501 for sidelights, H1 for main beam and HB3 for full beam.
just save up and buy HIDs mate, they last longer and look the dogs. the blue bulbs u can buy are rubbish as they only last a few weeks. its quite hard to get a good quality one, and the amount ur gonna spend on a philips or PIAA bulb is half if not the same amount as a HID set.
u dont have to fiddle with the projector part to get the bulb out. just have to undo the clip, pull off the rubber waterproofing ring, unlock the metal bar and pull the bulb out. the bulb is fitted to a white connector bit, DONT THROW THAT AWAY!!! u need it to fit the new bulb to. one fitted, just reverse the process.
i've changed my bulbs so many times that i can honestly do it in the dark without looking
