As mentioned u have to take off the Manifold,
There are 5 bolts ontop, undo them, then disconnect all hoses it will take abit of effort to get off.
When u take it off put a rag covering each of the 6 intake holes to stop dirt entering. All you have to do now is disconnect each of the coil packs to access the plugs.

Might pay to obtain (buy) a replacement gasket for the 'manifold cover' in case you damage to old one before you do the job.

Are the manifold bolts need to be done up with a tension wrench.
And is the job able to be done by someone with a bit of mech knowledge or do you need to be a qualified mechanic.
How do you get the plugs out (do you unclip the electrical harness and undo the one bolt to free the terminal from the plug?)

What are you referring to? tension?

Tension: 16-20Nm for the plugs.
