Most plaster will need a little prep, a light sanding with finishing paper (a white sandpaper used for drylining or a fine sand paper will do) Especially if the Plasterer has polished the wall which is common practice (it makes it better to see any small marks). Then get some trade emulsion (white) and give the plaster a blinding coat with the paint mixed with 70/30 paint to water and about half a mug full of PVA in each 3 litres of mix. Then depending on the quality of the Plasterer, you may need a little bit more sanding and a little bit of filling here and there, for trowel marks and divets. Then mix the trade emulsion with 50/50 of your chosen colour and give it one coat then finally give it a coat with your colour.
Use a roller for the best finsh cutting in with a 3-4 inch brush round the edges. if your no good at cutting in use masking tape.
This will give you a flawless finish.

All plaster needs to be sealed, I painted a bear wall with emulsion staight out of the tin, within six months the paint was flaking off the wall.
I would either, use some cheap white emulsion diluted with about 15-25% water and brush that on, OR brush on a PVA sealer diluted acording to the instructions on the tin.
Make sure the new plaster is really dry before applying, as long as six weeks if its cold, quicker in summer.

DO NOT PUT PVA ADHESIVE ON BARE PLASTER!I am a professional decorator so I should know what I'm talking about. If the walls are thoroughly dried out then simply apply a 'mist coat' ie a thinned down first coat of a quality trade, not retail paint {go to a decorators merchants}. follow the instructions on the back of the tin and you shouldn't go wrong. Then apply one or two coats of neat paint. Also buy a good quality synthetic filament brush {purdy is my favourite line} for emulsions. DON'T use a natural bristle brush.

Once its dry ( ie the plaster has gone pale pink ) I'd coat it with either a PVA sealer, or 50:50 watered down emulsion.
Either will work to seal the plaster and stop your top coats soaking in too much.
I use the emulsion as it helps with a more solid colour.
A good plaster will not need any prep.
Use a large soft brush and a Pretenders CD

for starters do not ask anything at b&q you may as well ask your wall. if your plasterer was any good you will not have do any prep work. find your local CROWN decorators centre they will give you all the advice you need. i paint new plaster all the time using mcphersons emulsion most of the time you can get away with one coat though two looks better.

You need to prime the plaster first and then go onto paint it. Ask at B&Q they will tell you what you need in one trip.

I find the best way is to water down emulsion about 50/50. this will seal the plaster. or you could water down p.v a ,roll it on the walls/ceiling. this will also seal it. leave to dry 24 hours.

You will need to seal the new areas. Get to Home Depot/Lowes and get some "Kilz". That will seal it. Put on two coats and then you can paint over it.
