part numbers please + surging vehicles

I'm going to take Highroller's advice and replace a few things to see if my intermittent "surging/jerking" will stop. He replaced the VAPOR CANISTER, VAPOR PURGE SOLENOID, and the VAPOR CANISTER PURGE VALVE and so far it has worked!! I was wondering if anyone could give me some [delco] part numbers for these parts. (1999 lumina LTZ, 3.8L, VIN K). I went to two parts stores today and they looked them up but they were called something different. They had DURALAST vapor canisters for $69, and a "canister purge solenoid" which was $19.99. They were unable to order a "canister purge valve."
If my memory serves me right, HIGHROLLER, used all DELCO parts. If anyone can get the part numbers for these I would sure appreciate it...
Also if you can tell me the correct names for the parts that would be just fine!
