removing load bearing wall

hi all am looking at removing this wall that separates the lounge and kitchen .
i've been doing some research as to how i'm going to support the ceiling when i remove it i've come up with what i think is something like what i'll have to do. so i've included some pics so you can see what i am trying to acheive.

first step - put up temporary supports for celing beams either side of wall

second - Remove wall and install 2 jacks studs next to king stud one end.

third - install new timber support beam

fourth - install jack studs at other end


each red line represents 1 stud in the pics and the beam at the top

am i somwhere near or not at all :?

also what detemins the width of the beam the span is around 4.5 metres.
