What to use on corner where two plasterboards meet?

[and1c]

ok guys.
I'm currently in the process of building a new stud partition to create an en suite bathroom in the corner of a very large double bedroom.

I would like to you know what is best to use at the external corner 'joint' where the two end pieces of plasterboard meet please?

Basically I want the new partion walls to be ready for a plaster skim when the plasterer arrives so I want to make sure Ive got it right!

Also, do I need to do anything where the plasterboard starts from the end studs (where it meets the current brick wall of the room?

Im aware of corner beading (metal or plastic(not so good Im told)) and corner tape but Im not sure what I should be using!!


Thanks

Metal corner bead is what you need £1 a length from B&Q
