Did you buy a gasket kit or just the head gasket and head bolts??
Reason being, you are gonna need inlet/outlet gaskets and outlet manifold to down pipe gasket.
You are also gonna need a torque wrench and you should get the torque settings and bolt sequence with the new head gasket. You are possibly gonna need a Ribe tool too for the head bolts, although the AGG possible just use standard hex bolts.
Set your engine to top dead centre to start.
You want to remove as much as you can from the bay to make your life easier.
Disconnect the battery, remove the air box and air intake pipe.
Drop your oil and coolant then remove all the vac and coolant hoses from the top of the engine.
Remove the intake manifold (you can leave the throttle body connected to the intake) and the outlet manifold, remove the rocker cover, auxiliary belt and cam belt cover, now remove the cambelt.
You need to remove the head bolts in sequence too, the opposite way to which you have to tighten them.
Once the head is off, clean both faces thoroughly, you can check the head with a straight edge for warpage, bob the new gasket on, put it all back together.
A Haynes would probably aid you in this quest to be honest, take a lot of pictures on the way to help you put it all back together
I may have missed summat but its a rough guide so hope it helps
