To get a gravesite pass, you have to park in the parking garage and walk to the visitor center. They will issue the gravesite pass and a pass to get out of the garage for free. Here is the site that explains about the gravesite pass but, again, I would suggest calling to get more information.
Arlington National Cemetery | Vehicle Passes for Gravesite Visitation
You should not need a pass to attend a service. When entering ANC, do not turn left into the garage. Continue straight to the guards. They maintain a list of services for the day. With the name of the deceased you will be allow to proceed to the administration building where there is a family room to gather prior to the grave side service. At the service time the visitors will be advised to get in their vehicles and follow the hearse to the appointed section of the cemetery. If full honors (Caisson, an Escort Platoon, Band) are being rendered the hearse will stop a section or two away from the grave to transfer the coffin to the caisson. Usually all other visitors will go to the grave side while family walks behind the caisson.
Close family will be issued entry passes so they can visit any time the cemetery is open, driving directly to the grave. After the day of the service all other visitors must stop to get a day pass to go to the grave site.
