Ok kokey you need to have an air gap between the roof and the insulation. So if the roof joist is 5 inches deep then the insulation board would be 3 inches thick. The thicker the insulation board you can use the better but the more expensive. Coolag insulation board is bought in sheets 8ft x 4ft. You just cut to size with a saw and insert between the roof rafters. Use 4x2 wood to make stud partition so you dont go all the way into the corners. Once all in place sheet with 1/2" plasterboard tape and paint. Job done.

You will need to install Styrofoam air chutes before the insulation. This will allow air to circulate on the wood on the roof. They are made for either 16" or 24" center rafters/trusses and are 4' long. Lowe's/Menard's carries them. They cost about 2.50 each. After you install them, apply your faced insulation with paper side facing the room. Staple the paper to the SIDES of the rafters/trusses.

If you are in the UK there are strict building regulations for loft conversions, you will find that it is not just a case of insulating the ceiling. Under fire regs you will need to replace all the doors to fire doors. A escape window will be required plus correct approved access, I am not trying to put you of just making you aware of the legal requirement if you wanted to sell. Remember if you add a window the council will no its been converted without permission.

if your rafters are old they may be only 3in deep which is unsuitable to install insulation and provide airgap. one solution is tri-oso. this comes in rolls and is stapled to underside of rafters, counterbattened then plasterboarded. is quite expensive about £200 a roll but quicker and less messy and wasteful than celotex board or similar product.

Don't use spray on foam. It was a bad news item on Watchdog last week. If done badly it can pop your tiles off. http://www.bbc.co.uk/consumer/tv_and_radio/watchdog/reports/homes/homes_20070220_2.shtml
