Bug eye wrx 01 3" TBE

Ok my car needs a service i got all the bits from my work all the right parts and when i go to put the plugs in HAH the ej20g ? Has coil packs on the heads which also seems impossible to change the plugs unless you dropped the engine or ripped half the powersteering etc etc off Any explainations on what the process of changing plugs is ?

My clutch has started slipping....Ive scourced a kit for $250 just need it installed what pricing am i looking at and does anyone have a number of a workshop who i can call (Good name)

And lastly just installed a boost guage, 3" TBE is the only mod and the resinator box removed from guard what boost would i be running stock ? Its spikes to about 13psi on cold days Sorta new to the whole turbo thing
