Fairly simple to do, for the rocker cover you need to unbolt all of the bits from the top and the boost pipe, pop the coil packs out then undo all of the 10mm nuts..i re-used the original gasket as it is rubber and will re-seal.
For the inlet you need to unbolt the throttle body, pop the pipes off from the underside of the mani, undo the bracket that supports it and then unbolt from the head..would recomend using a new gasket or even better installing an insultaor gasket from the likes of Badger5
