Pick an inspection centre and go there. They are all much of a muchness. As in every other thread you would have found in your search, some guys prefer one centre, others prefer another centre etc etc etc. You wont get a FIRM answer here.
My suggestion is make sure everything on your car is passable (BOV, ride height etc) and make sure everything works (headlights, horn, brake lights etc) , give the car a clean up and make it look respectable.
Then, go to the pit closest to you and good luck to you.
Cheers
